Fansof_heo May 20 2022 12:03 pm This drama is good but it just felt like it dragged too much after Jung Ho-young died. The episodes for me were doing the same thing and not catching the real serial killer. Probably could've decreased the number of episodes

Rainz Sep 28 2021 2:31 am I expected a lot from the drama because of the praises. However, it brought me a lot of disappointment. The first half is fine, but the second is too diffuse. They reveal the killer too soon which makes the drama boring. What is the point of using yourself as prey but don’t notify police? And I also cannot understand why other characters have to scare and follow the killer’s words?

hi Sep 24 2021 10:48 am It was going good in the first half, don't know what hit the writers in the second half cuz so many situations could've been easily avoided if the smart characters made smart decisions, so surely there were flaws but i'm satisfied with the ending. It's not the best for me but i can't really hate it. Also maniac duo and sensory duo were really funny

Zeus Sep 09 2021 6:38 pm Amazing series! A must see! Suspense and heartwarming! Very good and impressive story. Top acting of all the characters. I highly recommend this top series, you will not regret it for 1 second!

David Sep 05 2021 12:08 pm Even the ending was not beautifully perfect, but I admit that it was pretty good.

In this drama, I can learn that something had destined to be happened, but also something can be changed. Like what did Park Gwang-ho do in the past (when he traveled back), it can bring impact to the present time (2017)

Thank you for the good drama, surely worthed it to watch

Dee Aug 25 2021 9:15 pm I watched the whole series over the last 4 days. The actors and actresses were exceptional in bringing the audience into the characters world. The writer(s) were brilliant in this story.This was an intense series with dealing with psychosocial pathology of evilness. Again an excellent series that had my attention.

na dee Jun 02 2021 7:57 am tbh I watch Tunnel just recently bcoz of too much procrastination if I will like it or not coz I took so long to move on from Signal whom I love so much. At the end of the day, I find Tunnel as Episode turner kDrama, I needed to sleep coz I'm working long hours but I can stop my self from watching it. I love Jin Hyuk oppa since Heirs days but I found new love Oppa in Hyun-min with Tunnel. Actors are well commended, but just like any Kdrama some of you may find it boring and consist of lots of loopholes but please give a try. Who knows, Just like me, You will surely chooses to watch another episode than to sleep.

Jaine Mar 21 2021 8:42 pm Really great drama. Tunnel was terrific for a couple reasons. 1) The lead was very believable as an elder to the younger guys in the future. The way he spoke and maintained the role was admirable. After awhile it was easy to forget he looked young. The ending was so superb that I have watched it several times. It was brilliant and I will watch the whole show a third time. It is great writing when you want to go back and rewatch to see what clues are in the subtle nuances of a complex plot. 2) The secondary lead cop was so believable that I have looked for him in other shows. He balances out the story with the proper shock being in such a strange situation. Thank you!

EN Feb 27 2021 11:06 pm Best Crime Drama So Far!!!!!!

I've already watched a lot of crime korean dramas including Signal, Voice Series, Criminal Minds, Life on Mars but Tunnel is my favorite. The big case here is they need to find a serial killer but aside from that, the drama has small cases in every episode that is why I really enjoyed it! It's the best detective drama for me.

Glad that it's already streaming on Netflix! It's now the time to watch this drama if you haven't watched already! :)

You're welcome in advance!

Gomathidhanapandian Feb 05 2021 9:18 am The first 6 or 7 episodes made me feel boring and afterwards this drama got its full speed. Really worthy to watch.

trogon Feb 01 2021 7:01 am This drama takes a while to figure out what it wants to be. After the first couple of episodes, it nearly drops the time travel/serial killer plot entirely and features several episodes in a row of basic police procedural stories. One might almost suspect that the writers hadn't yet completely plotted out the main story and bought themselves some time by filming filler episodes based on some generic cop-show scripts they found sitting in a drawer somewhere. But around episode 7, it's as if the writers remembered what the series was supposed to be about, and from that point until the end, it's a much more tightly woven narrative and is actually quite enjoyable. So while it's perhaps asking a lot of the viewer to wait patiently through 6 hours of mediocrity until the show picks up the pace, it ultimately becomes a rewarding experience for anyone willing to do so.

Hyunjin Jan 27 2021 5:04 am That's why you can't trust everyone and has a limit. Kim sun jae shared everything to the doctor. How can he call himself a police? He should just keep between his team. Like I said, we has limit

Pamela C Etie Dec 31 2020 7:43 pm I loved this show so much! I was binge watching it in the middle of the night forsaking sleep! I laughed, cried, got mad at the killer, etc. I fell in love with the characters. I can't praise this show enough. The importance of love and family shine through. O just might watch it again!

Sini truman Nov 23 2020 7:11 am Spoiler alert..... Actually I like this drama. Initially it was slow but later on it became interesting. But I have a doubt regarding the plot. On the end of story the hero had gone to past and accidentally he had left the pen[evidence]in there. Fortunately the pen was kept by his daughter. But if this happens the present also changes right. So that the pen should have lost by the killer[doctor] in the past.so there is no way , DNA of recently [present ]killed people in it. But I think in this drama they analysed the pen and had found DNA of recently killed people in it

Sunny Nov 15 2020 10:35 pm Very good don’t hesitate to watch. People who give this drama bad reviews are definitely People who like to watch chessy dramas with 5 boys falling In love in one girl and just chasing her. There is a lot dramas like this just pointless but this drama Is just perfect and really good . Everyone acting’s is good i like That drama is not focused only in main lead Watch it and if you dont like it thats mean the drama is not bad but iy is not your taste

Sarng Nov 15 2020 10:30 pm This drama is really amazing. The story is so good and interesting. It is really hard to find drama with good quality like this one

H Oct 06 2020 1:17 pm Watched this because I was interested in Choi JinHyuk after watching him in The Heirs. Man the 180° turn in his character surprised me haha his acting was great and believable in Tunnel although the character itself lacks depth and can be too flat, which probably caused by the writing.

The drama itself was okay to good, not a bad one because it's still entertaining, but also not a great one because of various reasions, one of which the connections were very "fated" that made it cliche and draining.

Name Sep 18 2020 1:45 pm Spoiler!!!!

The way the main killer found outs parks 30 real identity ruined it for me. Seemed lazy tbh. No on in their right mind would guess someone came from the past unless that person had some physical proof. Idc if the killer is crazy smart. Nah bruj

b Jul 12 2020 10:05 am this drama is a great one, definitely not a waste of time.

for some people here, the plot twists may not be that shocking but for me it was, maybe it's because ive only watched a few dramas with serial murders as the main topic (although it is one of my most favorite kdrama topics, but unfortunately, ive only watched a few, most of those are meh ones, i.e abyss).

SPOILERS.

the plot may have been a bit predictable, and kim min sang's character was very easy to figure out, since in the beginning, there was something off in his aura. jung ho young was a very interesting character for me, and him being a witness caught me off guard.

the scenes in this drama that i enjoyed the most were always the ones with shin jae yi. i always got excited when she provokes the murderers. she definitely stood out. for me, sun jae and kwang ho's characters were plain, but nothing's wrong with that.

what i found the most interesting in this series were the murders themselves...

i guess the reason that i love this drama is because ive only watched a few of the likes of this. but im gonna watch more.

no one was a miscast.

i recomment this to people who havent watched this type of genre yet i guess

PinayNoona Jun 10 2020 6:02 am Coming from Voice, Signal, Memorist, Black, and a lot more dramas with the same genre...I have high expectations for this drama. But I am disappointed. I don't feel any tension between cases and Sun Jae's character was just plainly boring for me. Tunnel has more cases than Signal but Signal is much better and heart-breaking than this. Sorry I am not impressed.

Dylan May 14 2020 5:15 am I enjoyed this show a lot and I personally don't think Choi Jin Hyuk was a miscast. Maybe because I don't know Korean but nothing felt unnatural about his dialogue, just the character's personality.

jd Apr 30 2020 12:35 am usually ocn kdramas are a bit too cold but this one was very heartwarming....i'd say the whole time travel detective thing reminded me of 'signa'l but they both have very different plots...(also its been 4 years and im still waiting for signal szn 2 TT)

jd Apr 30 2020 12:27 am the first episode was boring ngl but it turned out to be one of my favorite kdramas i love love it

Army Apr 09 2020 8:49 am I love it so much

Dora the Explorer Feb 07 2020 10:39 am just finished watching this drama.. well, there were flaws obviously but the storyline’s fine. some of the story are easy to predict if you’re used to watching genres like this. since i have watched a lot of ocn dramas when i was a kid, i’ll give this drama a rate of 7.5/10 but if you’re still not satisfied after watching the whole season then i highly recommend you guys to watch the following dramas that i truly respect from ocn:

• Special Affairs Team TEN (one of my ultimate favorite) • Bad Guys (this are just so lit) • Black (plot was great but there’s just too much love story) • Kill It (also the best) • Missing Noir M (mind blowing cases) • The Player (this feels like ocn x tvn, amazing characters) • Save Me (this shit stressed me so much but still daebak) • The Guest (same as Save Me, fucking ???) • Voice 1 & 2 (no words can explain this one,,,,,, ??)

Depy Jan 26 2020 10:40 am My expectation is really high before watch this series, cause all the praises and fans. But it turns out so boring, the character's relationship easy to predict, the plot is slow. I'm sorry but for me signal is still the best time travel and detective series.

Dalagang_Pinipilahan Jan 03 2020 10:28 am I rewatched it after a long time and noticed the flaws I didn't notice the first time I watched it. Nonetheless, this is still one of the best K-Dramas to consider. There's this fight scene where Hyun Min deserves an award. Just impressively done and the best man to man fight scene I have ever watched in a KDrama.

Zad Dec 16 2019 8:27 am i'm sci-fi addict, especially time travel thingy, and this series disappointed. too many flaws, such as plot holes, character inconsistencies, and miscast. For me, Choi Jin Hyuk is a miscast, and so, it's an big flaw for the series. He is a good actor, but not in this one. too many unnatural line or dialogues and expression.

papergirl Nov 23 2019 6:57 pm unique story great drama i enjoyed this series impressive ^_^

Charmaine Nov 16 2019 9:41 pm What a great series ... I especially was very impressed with the actor's ... they were so true ... the emotions , facial expressions , body language .... all of it was superb

SYL Nov 12 2019 11:10 pm such a heartwarming drama packed with suspense! it’s a must watch for sure :)

Nadia Oct 27 2019 9:52 am This drama is predictable and the characters are frustrating. I'm developing bald spots watching these detectives work (pulling my hair out). And, why is the Violent Crimes Unit investigating robberies and arson cases where no one was killed or injured?

I've yet to watch a crime kdrama where the detectives aren't dimwitted and useless.

If I were one of the serial killers in this drama I'd be pissed off and frustrated too *makes a face*. The drama is slow. I could skip through a whole episode and miss nothing because they repeat everything at least 10 times in an episode and then some more in following episodes.

Kgm61m Oct 19 2019 3:41 pm I really enjoyed this drama. I loved all the characters and their stories.

Shunxing Oct 11 2019 8:20 pm I love Korean dramas as well. This one was a bit off at times and almost easy to figure out. I’m not completely finished yet. I’m watching on Netflix. I’d wish they’d replace all the bickering over who’s more supporting and superior with actual crime scene footage. Not much forward thinking for these smart guys. The detectives could have been more clever. I think that would have mad it more interesting.

Erdem Oct 08 2019 12:30 pm It was a great drama but i dont like the ending. They could show the old version of main character in somewhere. All things in the past effects future but they skipped that part in the ending. Proffessor Shin doesnt remember the her past and i thought it was connected to time travel. Gwang ho went past and do things diffrently but they didnt show us to what changed and how diffrent the present time now. It could be better if they showed that part as an epilogue.

Just a Fan Sep 17 2019 8:49 am Tunnel is a great series. The main story is exciting and it's interesting how the characters are related to each other in the future for the thrill of the story line haha. Kim Minsang is great as the villain though I just knew that very first exact moment he appeared in a scene he'll be a bad guy, his whole aura just seemed off.

Gwangho's hardwork as a detective is very dedicated and admireable, and I just love his chemistry with Sunjae. The chief is really cute and very loyal to Gwangho. Gwangho's wife is a literal angel, after all the hardship her trust never wavered. Though I think Taehee and Minha as partners is really a wasted potential. They both have their speciality but those never really contributed to the cases, just things they would have eventually find out anyway and not very critical. It would have been nice to see them use their speciality to full potential leading to some solved cases.

Ann Jun 08 2019 6:44 pm One of the best drama! In two days I finished watching it. Once you start watching you can’t stop!

Ara Dominique Dec 22 2018 5:57 am It has been such a long time since I have finished a Korean series because I usually got bored in the middle if the story is too predictable and dragging. But for tunnel? I love ALL characters, I love the storyline, I love everything! Thank you for giving us such a masterpiece and more series like Tunnel please..This is the best OCN drama series I've seen and definitely one of my faves I'll never get tired of rewatching along with Baby Faced Beauty, Sungkyunkwan Scandal, Mystery Queen, Sensory Couple, and School 2015 :)

snydez Dec 14 2018 9:06 am the first korean drama i ever watch. and it is the best

irfan Dec 08 2018 2:48 am recommended drama..all plot twist and conflict = legit..standing ovation for kim min sang, he steals the show..

DJM Aug 26 2018 10:11 am done watching today :) this drama is superb i'll give it 10/10 :) i love the twists of the story. i love everything :)

RK Aug 17 2018 1:41 pm Season 2 pleaaaseeee!! :(

I CAN'T EVEN SLEEP FOR LIKE AN HOUR BC if i have done with 1 episode I WILL GONE TO THE NEXT EPISODE LIKE ABSOLUTELY. everyone whoever read this. TRUST ME. y'all never gonna feel regret to watch it.

AJ Jun 17 2018 4:14 am One of the greatest Korean dramas. Fabulous cast, writing, direction, and a score plus sound effects editing that is so gripping it is like another character in the story. Two killers, one quite typical and scary, the other an even more terrifying surprise. And a complex, touching background story that takes time slip to another level. Truly a fine series any country would be proud to claim, and once again, it is Korea.

Alecie Jun 05 2018 12:52 am I just watched it ! Damn i want moree huhu

kendrew0406 May 11 2018 12:45 am Just finished the drama today. I initially planned to watch this drama because N (VIXX) is my ultimate bias, but then, when I learned that this drama is also nominated for the Best Drama of the Year, I realized that this drama must have been really good and different from the other dramas the Hakyeon starred in. I wasn't disappointed at all. The casting, plot, and settings are really good. Also, loved the connections between the characters, and each extra case that were tackled all have some sort of connection to the original case.

rendiishere Mar 17 2018 1:18 pm spoiler

really, pls dont read this if you havent watched it.

@Tara Young, in my opinion, first of all there are already many different timelines/parallel universes going on, so basically "tunnel" provides a wormhole to another timeline "theoretically of course", just like in narnia, alice in wonderland, even in interstellar, but in "tunnel" there are branches caused by actions of some key persons in the story, so i think its more like x-men day of future past or tv series "community". in short, i think it goes like this:

1st timeline, the one when kwangho enter the tunnel in 86 and travel to 2017, years behind him happened as if hes gone or considered as dead, the one with his wife died, his daughter got adopted, the main plot so to speak

2nd timeline, when he went back to 86 again, the first alternate universe is created in which kwangho forget the pen and he chase the young prof mok and went back to 2017 while in 86 and moving forward his wife found the pen and sew it inside the doll and it ended up in yeon ho's hand up to 2017. this timeline is now considered as main timeline. i think after kwangho is gone for the 2nd time, life goes on like the 1st time hes gone, which means, yeon sook still dead by accident, yeon ho got adopted, with only slight change in the existence of the pen. so its like A to C directly at first but this time A goes through B first then to C. 2nd timeline ends up to the prof getting caught.

3rd timeline is when kwangho got back for the last time leaving 2017's sun jae, yeon ho, shun sik etc. i assume he successfully caught the 86 young prof mok, (i do hope this plot is included in the drama, i felt that the drama is dragged for unnecessary turns leaving 1 ep to wrap things up quickly) anyway, after the young prof mok is jailed, it continues up to that scene in 88 where he met the future corporal park.

tv series and movies about this topic is perceived differently among the makers, including this one, i dont know what will happened to each existing timeline, whether they got erased or still exist, in tv series "community" every actions can creates many different timelines, not necessarily has to go through wormhole like tunnel, but in narnia/alice in wonderland, you need to enter something like tunnel, in interstellar a blackhole is needed, in back to the future you need to make your own device to transport you to time travel..

tunnel and signal are interesting, the finale is a tear jerker, i hope many more of this genre from kdramas not the overroduced rom-com mushy lovey dovey kind of dramas with sooooooooo predictable plot

Tara Young Dec 15 2017 8:51 am Very interesting drama and well entertaining as I always love this kind of crime & suspense drama. Little things that I felt a bit missed out is when Gwang-Ho went back to the past (1986) and reunited again with his wife Yeon-Sook (he said that he wanted to prevent Yeon-Sook's death and give his daughter Yeon-Ho/Jae-Yi a better life), but in Jae-Yi's present time, nothing had changed (Yeon-Sook still died) and no one questioned this, I thought that perhaps there was some parallel dimensions/worlds theory but it turned out not, only some memories had been altered. The other thing is when they successfully caught the murderer (Jin-Woo) in the future (2017), I wish Gwang-Ho could prevent 30 years serial murder/save some future victims by catching young Jin-Woo in 86 as he already knew who the murderer was. I also wished that there would be a glimpse of Jae-Yi's life in the future as his father reunited with his wife is shown, perhaps with old!Gwang-Ho and old!Yeon-Sook seeing their daughter living a happier life and no longer as orphan or does the car accident still happen to Yeon-Sook despite Gwang-Ho back to 86? Otherwise this is a well done drama.

horasy Dec 07 2017 8:41 am very amazing drama... ? love this drama... so much

regina Dec 05 2017 5:22 am just finished watching this drama, it’s really awesome! not really a fan of dramas, i accidently watched it on my cable tv while flipping through channels and found it very interesting so i decided to continue watching. really love the psychology complexity of the story though!

jasmine Dec 04 2017 6:12 pm Very fond of this drama... Hv been watching this superb drama since the 1st episode..

Merdeka!

respito Dec 03 2017 2:58 am Love this drama. It's certainly worth watching.

sandy Nov 29 2017 9:06 am nice drama

bang jehoon Nov 21 2017 3:22 am is it kinda similar to "Signal"????

nadkorea93 Nov 16 2017 6:05 pm worth to watch.. recommend ..

LL Oct 13 2017 1:26 pm The drama has an engaging plot, outstanding casts and good cinematography. Each episode will keep you on edge. And surely, you'd want to finish the whole thing in one go. I generally like it, but some things bothered me. Some parts have questionable writing and sequence. The characters also sometimes lose their critical thinking, when they are supposedly established as sharp and rational through most of the drama. I guess it's something that's common with similar dramas lately (like Voice and Signal).

Saman Sep 21 2017 2:41 pm one of the greatest dramas in 2017..if you haven't watched it you are missing a great drama..must watch!!..I'd rate it 101% if there was ;);)

MGL Sep 11 2017 11:36 pm Hello, good folks of Korea. Greetings from Mongolia! I would like to ask something about this Kdrama. There's a song that the serial killer sings at ep.8 when he memorizes his teen ages & he kills a student. It might be some late 80s Korean song. I would like to know about this song. If somebody knew the name of the song, please comment. p.s sorry about bad English

sushi12 Sep 05 2017 3:19 am Every minute is a thriller! Omg i just can't stop when i started watching. At times i wanted to fast forward to watch but i could miss out lots of details! And Hyun Min is such a sweetheart ❤ Didn't regret watching! Tunnel and OCN dramas never fail to disappoint me. :)

Noor Aug 26 2017 8:29 am Omg ????????? it was the most beautiful drama in my life i really love this drama love love love it ❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤

hallyufan101 Aug 12 2017 9:52 am I just finished today! It was amazing! No seconds, minutes, scenes, or episodes that disappoint me. I have moments that I really want to drag the episodes just to know who the murderer was, still I able to stop myself, and guess what, I predicted who the murderer was, so proud! Love the ending as well.

hallyufan101 Aug 12 2017 9:49 am I just finished today! It was amazing! No seconds, minutes, scenes, or episodes that disappoints me. That moment when I really want to drag the episodes just to know who the murderer was, still I able to stop myself, and guess what, I guess who murderer was, so proud! Love the ending also.

soso Aug 11 2017 2:09 pm OMG ... still aim in episode 2 and really its amazing drama i love it

rara Aug 03 2017 9:57 pm Ah, this drama's one of the best I've seen so far ! The plot is really good ! But I can't seem to find the actor who did young Mok Jin Woo ? Does anyone know who it is ?

astri Aug 02 2017 4:17 am great drama tense to the end

Uckezzy Jul 16 2017 2:48 pm Best time travel drama i ve ever watch..The plot was very Interesting and Understandable..Every Episode just keeps you at the edge of your seat and the cast were brimming with life in Every Episode...Highly Recommended and it worth the Watch..

nancy Jul 16 2017 9:12 am @Gail tunnel drama highly recommended must watch

George Jul 12 2017 4:57 am So far.. this is the best time traveling and detective drama I ever watched. The plot is not only interesting but the characters behind the story is applausable. The best part here is the daughter and father scene (The awkwardness between them can make your emotion ups and downs). The couple with few words. I know its wierd but the romance between Sun Jae and Jae Yi is not so typical but they are cute though. To the crews and cast behind this amazing drama.. You all did a great job to carry out the potrayal of each character The best! keep it up..

Gail Jul 10 2017 4:17 am Intersting plot. I think I started to love travel time drama bacause of The Best Hit. Should I watch it??

Carol maloney Jun 26 2017 1:02 am The absolute finest detective drama series! Excellently acted, really moving and so well paced. It is one of my all time favorites...heartily recommend it...10 stars!

Wendy Jun 25 2017 6:22 pm This drama is full of surprises..The best...

nancy Jun 16 2017 1:07 pm After watching tunnel....... Move to time travel drama the best hit on going. ....must watch drama

nyopsss Jun 13 2017 11:57 am Before I saw this drama I have done to watch Signal. I think Signal is the best drama. But Tunnel same with Signal. Both of them have the great story and made me fall in love with crime drama.

Ps: sorry for my bad english

dia Jun 12 2017 1:52 pm is there too much love story in this drama? or a kiss scene? I love crime/detective drama but im so suck with too much love scene/kiss scene. everyone please tell me =)

Maira Jun 10 2017 12:41 pm one of the best crime drama amazing cast with perfect acting Trust me ... it'll worth your time especially for ms. Lee Yoo young ... you deserve an award.

K Jun 05 2017 7:01 am Love it!!

Nyit2 Jun 01 2017 4:36 pm Amazing drama....recommended

Annaberry Jun 01 2017 9:50 am Excellent drama !!! Must watch

Charm May 31 2017 3:10 pm They should give N a big role in this kind of drama. N being a detective or having a serious role fits him perfectly. Cha hakyeon is not only good in dancing, singing, leadership he also have talent in acting.

Mblaq-MadTown ^^ May 31 2017 12:15 am excellent drama 100% recommended

Judith May 30 2017 5:46 pm Excellent time travel, as long as you are not picky about discontinuities. Sweet story, well written. Great acting, cast was all excellent. Ending was emotional but not tacky. Worth watching.

Astrid May 29 2017 4:40 am don't you guys think there should be a extended ending, where kwang hoo,yeon sook growing old happily with shin jae....... i think the ending was not enough... just my opinion

ps:sorry for my bad english

Jenny May 29 2017 12:04 am Exciting drama. Good plot and great acting by the leads. Lucky i did not miss this drama. Its now in my favourite list for the year..

Momo May 28 2017 8:34 pm My friend said if you like Signal (in which I absolutely adore it) you'll love Tunnel. So, here I am, looking forward to this drama!

Jenit May 27 2017 3:19 pm I agree 100% with people who are encouraging others to watch this drama. I didn't like much fictional dramas in the past,but after watching some (Goblin, The legend of the blue sea, etc) and now Tunnel I really appreciate not only the plots but the great acting too. Don't miss watching Tunnel!!

SM May 27 2017 12:44 pm If you're looking for a time-travel drama with a pinch of crime and mystery, this drama is for you. Every character is special on its own and heartwarming too. Couldn't ask for better casts because seriously, the casts did a superb job portraying every emotions. Every emotions felt real and the final episode made me cry like a baby :'(( Choi Jin Hyuk's best acting yeapppp

Will miss watching you, Tunnel.

nancy May 27 2017 8:48 am Saturday day of tunnel.....I miss u..so much... I wish season 2. .With same cast

Olivia May 26 2017 1:36 pm This drama seriously just amazing and perfect ! The cast is awesome and perfect ! This drama was very very good with action suspens we laughed too ! i cant believe it's already the end. SPOIL : So at the end That's why the name of N was Kwang Ho beacause the oldest Park kwang ho saves her mother in 1986 whoaaa unbelievable and beautiful Thank You OCN for this drama 10/10

YoonHyunMin ? May 26 2017 3:29 am Give 5 thumbs up if i have for this drama

Wanderer May 25 2017 5:43 pm Watch this drama. I'm serious. It will keep you on the edge of your seat and have you wonder the craziest possibilities throughout. The screenwriter is absolutely amazing (and it's her first drama!!), and the characters are so fresh and interesting, this will feel like a wholly new experience for even the most avid drama addict. You will grow to love all of them, even those whom you should hate, for they have so much depth and character to them. I knew Choi Jin Hyuk was good, but I'll def keep tabs on the other actors too from now on. Also, I've never seen Jo Hee Bong in such an interesting and complex character before, I'm gonna look differently at him from now on.

This drama is a must watch. Get to it, folks.

Much love from Hungary.

Encik lari May 25 2017 4:18 pm Kamsahamnida tunnel team.. ??? It was awesome to watched for this year. Really enjoyed during night time with popcorn hahahahaha.. What can i say.. Hope will be a 2nd tunnel drama after this.

Matthew May 22 2017 12:29 am Who was the actor for young Mok Jin-Woo? Hats off to him for great acting. Drama was superb and dramatic, and had nice twists and turns. One of the better dramas with fantastic storylines, but would have loved to see more of the ending.

Kfan May 21 2017 8:51 pm The ratings prooved that this show is one of the best crime dramas.Everybody compared it to signal but i can surely say comparisons are not valid vecause bitg are quite different in their approach. But for me tunnel is best and i cried like a baby in last episode can we really have a better ending ...love you Choi jin hyuk you deserve to get an award for this

Hunter May 21 2017 7:25 pm Excellent acting everyone, the chemistry between all the characters worked really well, devastating bad guys, honourable good guys, exciting psychological twists. Job well done cast and crew :)

Mariane May 08 2017 8:43 am Ahhhhh.......Why there's no episodes?

Paul Edward May 07 2017 11:53 pm Why there are no episodes this week?

Just Jazz May 07 2017 10:32 pm Tunnel is a good drama. The best in his genre. Like much ^__^

nancy May 07 2017 7:27 am Tunnel highly recommend best drama Choi Jin hyuk fan..satisfied everything about drama story cast performance.... superb...LOVE IT 13 days waiting killing

Sweetaaangel May 06 2017 10:09 am So intense. I do love this sci-fi drama. The way they solve the cases, amazing ?

Song Ji Hyo(Fan) May 06 2017 9:04 am Really exciting! This drama makes my heart dugun dugun and makes me feel excited! This drama may not be the best (in suspense dramas) but this has the best plot! I really really want this to have a great ending. I have some idea on my mind and I think it would be great but still want to know what would be the real ending of this drama. Hope that the staffs(the script writer, director and also the artist) put a nice performance from the remaining episode up to the finale.

northerngirl May 04 2017 7:57 am Really riveting! A must watch for fans of Choi JIn Hyuk and suspense dramas!!

Rahma May 04 2017 12:34 am This drama is magically awesome. I know maybe so many other drama could be better or the cases they faced more fascinating but for me Tunnel is just too perfectly simple. The plot is not too complicated, not make us want a hurry ending and every case just finished quick efficiently but still enjoying every scene and episode here. I missed this kind of drama and Tunnel come to fulfill it.

Tezia May 03 2017 5:09 pm Great drama! I Love the twist and the suspense that surrounds it.choi Jin hyuk,great actor. Love him! Will like to see him More in drama .other actors and actresses were superb. Love this drama to pieces.

Floyd May 02 2017 9:42 pm This has been one of the most well made and well acted shows I've seen in a while! Can't wait to see how this ends.

Pan May 02 2017 9:35 pm OMG this show is insanely awesome! Plot twists are everywhere in the corner, plus, all actors and actresses are AMAZING at acting, especially Kim Min Sang. Lee Yoo Young is a rookie in drama but she did very good job. Overall this drama will make you mind blown from A to Z. HIGHLY HIGHLY HIGHLY RECOMMENDED!

BTSxARMY May 02 2017 8:28 am One of the best series I've watched so far! Everything about TUNNEL is just excellent!

Good thing that I'll be busy for BTS con here in PH this week cause waiting 6 days is killing me, what more with 13 days!

yanpark May 01 2017 6:18 pm They really nailed it! Such a really good plot/story…the twists..wow! You really got us there! In time of catching the culprit, Park Kwang-Ho returned to the past! How did it happen? Upon returning, I think he will look for a way back to the future or he will look for Mok Jin-Woo now that he knew him as the killer. Of course the people he left behind will get shocked, discovering that he is still alive. But how will the present characters catch Mok Jin-Woo if the only lead has gone back to the past?

If Kwang-Ho caught the young Mok Jin-Woo…the timeline will change, isn’t it? Kwang-Ho will stay in the year 1986, he and his wife will live happily and Jae-Yi will never adopt. Sun-Jae will never become a police?

Wow! Can’t wait for the next episodes! ^^

Lovelove May 01 2017 7:55 am Oh no.. 13 days more to watch the next episode (13&14) . cant wait :/ I really love this drama!!

Guiltypleasure May 01 2017 6:05 am Park Gwang Ho should inform letnan Kim or profesor Shin or Shung Sik first after knowing about the real killer, before going to the tunnel. Who guarantee he will safe after meet the villain, al least if he killed, so the police can arrest him

yasmin May 01 2017 1:48 am Oh my gosh!! I just done watched ep11&12!! park gwang ho go back to the past!!! Oh noo ? how about his daughter??? But if he go back to the past..he could save his wife?? Yeas I hope that will literally happened ? please save ur wife park gwangho!! I hate it bcs they didn't show the prev for ep13 ? some viewers said that ep13&14 will be postponed 2 weeks ? (sorry for my bad English!!)

Kori May 01 2017 1:12 am Such a excellent drama with a great cast. It will keep you in suspense

IwasBornIn86 Apr 30 2017 8:05 pm Tunnel is superb. I just watched ep12 and it was so exciting! Kwang Ho's acting is really ?!!! I'm sad that eps 13 and 14 will be delayed a week due to the upcoming election.?

redleaf97 Apr 29 2017 8:55 pm The latest chapter, funny how Sun-Jae trying to look as the nice guy as hard as he can in front of Shin Jae-yi. And didnt fought Kwang-ho in front of her.

yhan Apr 29 2017 6:53 am super b ! love this drama. waiting for ep. 11.?

mun Apr 28 2017 10:24 pm i got the feeling that there is something weird with the taxi driver that kwang ho meet right after he came to the future..how come he has the same face with reporter oh from 30 years ago?

Wen Apr 28 2017 6:33 am This drama remind me of "gap dong"

yasmin Apr 27 2017 11:41 pm I hate the fact that park gwang ho wife is died :(( i hope that he can go back to where he belonged and saved his wife!! His wife can't die just like that :((( I need a happy ending for park gwangho and his wife pls :((

nuf Apr 27 2017 8:57 am oh gosh!! can't wait for episode 11 . the thrill is superb!!

Daniel Apr 25 2017 9:41 pm This is the best drama in early 2016. choi jin hyuk acting is very nice.

DMPark Apr 24 2017 9:49 pm --SPOILERS--

Wow! Episode 9 and 10 was an exceptional episode! There are 2 killers! Jung Ho-young and Mok Jin-Woo! Daebak! So, Mok Jin-Woo knew the mystery of the tunnel. And that’s why he killed the present Park Kwang-ho, because he knew him. But the question is, how did Jung Ho-young knew the murder scene where Kim Sun-jae’s mother where murdered? It was seen during Jung Ho-young flashback. I think he saw the suspect killed Sun-jae’s mother. That’s why, he copy the way Mok Jin-Woo’s killed his victim.

But why did Mok Jin-Woo became a killer? There is a side in him that is good and bad. What is his story? Can’t wait to unveil his story.

And father and daughter will reunite…at last. I hope Shin Jae-Yi accept Kwang-Ho. Is he going to tell her? I hope so.

I recommend all Korean Drama fans to watch Tunnel. You will surely love this. :D 

shya Apr 24 2017 9:26 pm I must say this...How beautiful is choi jin hyuk's wife in this drama..she is very very pretty...Not to mention this drama always keeps me on edge of the seat. Impressed with Choi Jin hyuk acting & versatility.

Audrey Apr 24 2017 9:47 am I got a feeling that 88 Park Gwang Ho could have had gone back to 1986 and that's why he knew the case and somehow he was chase by the killer in 1986 and came back to 2017 through the tunnel.

loveheart Apr 24 2017 8:23 am I think i know the rest of the plot they find out that Jun Ho Young is just a copy serial murderer. The real murder is the autopsy doctor.

how? every aspect of the murder from 30 years ago was released and known to public accept the dots. the murder with the dots and the murder without the dots are different they are done by 2 different persons. the copy serial murderer can only get information from the article released. he won't know the real serial killer characteristics. thus, the murders committed by Jun Ho Young looks different from the murder that happened 30 years ago.

why the autopsy doctor? remember the murder that happen near the lake? the victim has 7 dots. but based on episode 9 the dots were not mentioned in the autopsy. you can say the same thing happened 30 years. but, that is what that was 30 years ago. now technology is very advanced. 7 dots on the heel cannot be missed.

another very obvious thing the doctor said "can the king be caught?"+ evil laughter means he is saying that the person who did the murder be caught?

also, when the real kwang ho got murdered and sun jae called the doctor to come he only said the general forest name how did the doctor know where to come exactly.

not only that every story need the bad guy to be caught right? both will be caught and the "fake" kwang ho will be reunited with his daughter (the psychologist )

I have a feeling the plot twist is that the psychologist died during the whole case somehow or rather. then kwang ho realizes that she was his daughter? that would be sad.

I have a feeling another person in the police force will be killed.

here is where i am very confused about the story. why did he travel to future? how did he travel to future is it really the tunnel than the murder from 30 years ago also went through the tunnel and kwang ho followed him right so the murder from 30 years ago and kwang ho traveled time together? also why 30 years? if he goes back which i have a felling he won't be able to (as death and birth cannot be reversed); if he catch the murder from 30 years ago 30 years later how will it change the past? also what will happen from there? they just live happily ever after?or will there still be a doppelganger? also why no one talk about the fire that burned all the case details about the murder that happened 30 years ago?

lot to think but will keep on watching it for any plot twists. thought after 40 mins into episode 9. i already know in episode 10 they might sacrifice the psycologist

this is a long comment here's a potato #9gag

Irfan Apr 24 2017 3:31 am already watch ep 10 and gettin more chill

anonim Apr 23 2017 11:31 pm Woow... This drama really makes me addicted after the drama "Signal". I did not think there would be two criminals...

Nici Apr 23 2017 2:15 am !!!!!!! SPOILER ALERT !!!!!!!!

Who already watched episode 9?!!! The forensic doctor is also the killer right? I think he was the one who killed women 30 years ago. Hmm.

nancy Apr 22 2017 4:56 pm Tunnel Highly Recommended..best...in every aspect Choi jin hyuk superb amazing......yoon hyun min talented......each and every character..amazing superb........ Amazing storyline......addictive.....can't wait for ep 10....also every ep waiting just killing....7 day waiting....killling...curosity....

Hunter Apr 20 2017 10:42 am I'm really enjoying this drama at the moment, it took a little while to build momentum but I am loving where it is at now and can't wait for the next episodes. Great story line and fresh characters.

nanchi Apr 20 2017 7:33 am i genuinely amazed with their acting skills, the plot of this drama is very interesting,

ㅋㅋㅋㅋㅋ Apr 20 2017 5:10 am This drama is very impressive! The plot, actors' performance, and everything are just excellent! Quite addictive!

Mp_Misao Apr 19 2017 10:52 am Tunnel is the best Korean Drama Series I've ever watch!! The plot is amazing,the actors and actresses are playing their role beyond outstanding and oh we cant forget the brilliant man behind all these the Director.TBH he's idea are out of the world!! Don't Forget To Watch Tunnel, trust me you'll be addicted to it!! ???

DiPark Apr 18 2017 11:15 pm After re-watching it last night, I think the killer is the present Jung Ho Young. He travelled through time and went to the year 1986. There, he killed women in skirts for pleasure? . . . to satisfy himself?

His younger self, committed crime by killing his neighbors’ dog and burying them in his backyard. Something triggered inside him to start killing women after he was put for questioning. But it happened later on, that was the time or rather it is in the present year that he started killing – he went back 30 years ago to commit crimes. What is exactly the mystery of the Tunnel? Hmmm…

It doesn’t make sense right?  It’s just my theory ^^

As seen in Episode 4, he was confessing that he can’t forget the time he killed the mother of Sun Jae. He said that he can’t stop….from killing . . . how tragic!

pgirlcl13 Apr 18 2017 7:54 pm What a Thriller past & present action pack drama, loving the way the storylines folding into watching till next episode & make the waiting worthy. I must say Choi J-H & other cast members are doing great at expressing this drama throughout. Pins and needles till the end, I am loving it

ADviewer Apr 18 2017 3:16 am Great episode! Waiting the next episodes... Fighting!

k2k Apr 18 2017 1:06 am whoa!! im super curious!! prof. shin is the daughter of yeon sook and kwang ho??? i cant wait till next week aarrgg!!

MillaAY Apr 18 2017 12:16 am if you like kind of drama , serial killer ? detective ? I recommend this one, the plot is fast, there is no boring scene, each episode has own story and make you curious for the next episode , never realize that one hour has left, i'am waiting for the next episode --- 9 and ......

yanpark Apr 17 2017 11:06 pm Wow! This drama is worth watching for!Great story & great actors. Watch it! Kim Sun Jae's reaction when he found out that Kwang-ho's from the past, and he's reaction also when he found out that Sun Jae is the baby whose mother was murdered 30 years ago. After that incident, Kwang-ho and Sun-jae are inseparable---protecting each other. How will Kwang-ho react when he finds out that Shin Jae-yi is his daughter? And how will she handle it? Did she still remember her mother? After all she's still young when Yeon-sook died and was adopted. I hope she is, and the necklace whistle, she still have it. And that killer, he's the one? Back then, when he caught for killing dogs and burying them in his house backyard, there is something off about him. But he has an alibi...has he? I think something triggered inside him when he was questioned by Kwang-ho years ago and happened again when he got caught by Sun-jae and questioned him. Good thing Prof. Shin Jae-yi is there, but there is someone stalking him, hmmmm...who would that be? So many questions....come Saturday and Sunday :) can't wait for 9 & 10.

Cindy Apr 17 2017 6:59 pm Great drama! I have enjoyed it so far. I too believe the forensic guy is the killer.

Madeleine Apr 17 2017 6:40 pm Great plot, writing, directing, acting. This one has it all.

LoneGunMan Apr 17 2017 4:51 pm Kudos to the writer. Aside from a tv movie in 2013, this is really the screenwriter's first big crime drama. Interesting how all the characters have links to Park Gwang-Ho. Keep up the great work! OCN and TVN are my favorite networks. They don't follow cookie cutter plots like the other networks.

bobby345 Apr 17 2017 1:40 pm by the way who is the director of this amazing drama?

jinjoo Apr 17 2017 9:54 am wow wow wow need i say more? this drama is just too addictive for me N amazing acting of my fave actor Cho jin hyuk! i hope he wins an award esp his performance in this latest epis 8 where he really was very touching N hard if you can't emote with that scene! 2 thumbs up waaaaaaaaaay up, all the cast in this drama are truly superb, good writing too! i can't wait for epis 9 nxt week! luv luv CJH! fighting!

chaNNN Apr 17 2017 5:26 am I'm pretty sure that the killer is the forensic guy. His name is always at 5th or 6th in the credits.

안딘 Apr 17 2017 4:24 am What if yoonseok had 2 babies i mean twin(?) it's park kwang ho who born in 1988 and jae yi (?) but idk lololol

Jay Apr 17 2017 4:00 am I start to thinking, who is 1988 park kwang ho? How did he know about the case? Then i rewind to the part when (old) park kwang ho with the chief went to the small village the last call from 88 kwangho call history. So i think the grandma that they didn't meet must had some kind of relationship with the case too. Or maybe there must be someone that 88 kwangho know that killed too with the case. OMG This case is so confusing but so addictive to watch.

Btw i guess it's true that prof shin is (old) kwangho daughter haha...

Kat Apr 17 2017 3:34 am OMGGGG! I'm so addicted with this drama!! Done watching episode 7 and 8!! Aahhhh I'm so happy that kwang ho(CJH) and sun jae (YHM) are now okay! I love it when Kwangho is always worried with Sun Jae! Aigooo i love the bromance!! Can't wait til Kwangho finds out that his daughter is Professor Shin Jae Yi!!! Aahhhh can't wait for next episode! One of my fave kdrama!

Joy Apr 17 2017 3:11 am I really love this drama! Very interesting!

Helenna Apr 17 2017 12:54 am It means that Profesor Shin Jae Yi is Park Kwang Ho's daughter?? So who is Park Kwang Ho who was born in 1988?? I guess he is also Park Kwang Ho's son. If not, why the serial murder killed him?? I cant wait for the next episode.

Same like Defendant, I really love this drama. On the first time, I was going to watch this drama because of Choi Jin Hyuk but now I am going to watch this drama because of CJH and also its drama story.

ST☆RLIGHT_아린 Apr 17 2017 12:48 am @Nici the 8th episode explains everything~ now I can't wait for Kwangho to recognize her :')

hurhurhurhur Apr 16 2017 9:10 am EP 7 WAS SO GOOD !! i literally have goosbumps nearing the end ! so far my favourite drama of 2017 :) i rate it 10/10 ! definitely recommended

ST☆RLIGHT_아린 Apr 16 2017 8:45 am Done with ep.7! The best episode so far, really.

[SPOILER ALERT]

Ok so now I'm convinced that Jaeyi is Kwangho's daughter since he can't help but care for her, but not in a romantic way.. and the mandu! Kwangho bought it since it's Yeonsook's favorite. When Jaeyi eats the mandu, it reminds her of someone feeding her. I'm pretty sure it's Yeonseok, her real mother before she got adopted.

What do you guys think??

If this prediction turns out to be true, it will be really cute imagining Jaeyi ends up with Sunjae.. which means Sunjae will be Kwangho's son in law! KYAAAA <33 Sunjae and Jaeyi are really cute but Kwangho and Sunjae are definitely cuter!!!! ^^

Anyway, at first I thought 88 Kwangho is Park Kwangho's son but now I don't think that's the case?? Who is he.. really.. our talented idol actor Cha Hakyeon.

CAN'T WAIT FOR EP.8!!!!

Aijo Apr 16 2017 2:37 am I hope the killers not the forensic scientist. That'd be way too obvious.

sych Apr 15 2017 10:24 pm This drama is addicting.. I can't wait for next episode.. This is gonna be the best thriller drama ever.. At least for me.. I like all the characters.. Highly recommended this one! Great storyline.. I don't usually like drama that involve with time travel but this one.. wow! it is great.. Best OCN drama ever! Thrill, love, murder, sad, time travel, friendship, family, funny sometimes.. Its great.. Idk what else to say.. Great storyline..

Kiki Apr 14 2017 1:06 pm It wouldn't be thrilling or fun if the suspect is the forensic guy or other police officer. There are too many movies or dramas with that kind of plot.

Maya Apr 14 2017 12:41 am I just love all of this drama, especially the chemistry bonding between Prof Shin and Let. Kim. That's so wonderful. How can be like that? It's look like they are really fall in love already.. I'm very excited where their love story goes to.

Mimi peri Apr 13 2017 2:59 am signal, gapdong,voice, tunnel, yes all of this are thriller drama if you think all this drama was same or copycat you just not watch it closely. or you are too dumb to understand thriller drama. every drama has their own plot & twist. and i'd love to enjoy all this drama in OCN. thanks OCN.

Wanti K. Pratama Apr 11 2017 10:00 pm drama with one word title is "really something" haha.. like signal, voice and now tunnel.. that's great plot~

nancy Apr 11 2017 7:49 am i love this drama so much highly recommended.....choi jin hyuk ...fantastic....yoon hyun min.. everything about this drama superb cast..story...love them.....that forensic dr..seems suspicious when he said some people hide in light instead of darkness and his special attension toward park kwang ho....and fact about kim sun jae..little boy i like it ..i already guess about sun jae by the ep.3........professor may be daughter of park kwang ho .....and the new chemistry btwn professor and kim sun jae.......and park kwang ho junior and in future cheif...love their relationship...tunnel drama the best......most important choi jin hyuk fan?

Dai Apr 11 2017 12:23 am I watched Episode 5 and 6 last night, connections 30 years ago and the present year are slowly showing up. The mother of Lt. Kim Sun-Jae was actually the woman murdered by the killer...daebak!! :) he was that baby! I only found it out when his father shows up wearing the necktie that supposedly his wife will give him. Wonder what will be the reaction of Kim Sun-Jae's father if he meet Park Kwang Ho. hmmm...

What I'm waiting for is how will Kim Sun-Jae handle the situation if he finds out that Park Kwang Ho is from the year 1986? And that Kwang-Ho handled the case of his mother and couldn't find the suspect.

And Professor Shin Jae-yi is Kwang-ho's daughter?

They are partnered with only one goal, to find the killer and to unveil the reason behind his killings and the mystery of the Tunnel which brought Park Kwang-Ho in the future.

Kat Apr 10 2017 7:42 am Done watching episode 5 and 6! Every episode is worth watching! Can't wait for next episode! Exciting scenes with Choi Jin Hyuk and Yoon Hyun Min! HyunMin is so cute when he smiles! Can't wait til Hyun Min(Sun jae) finds out the true identity of Jin Hyuk (Gwangho) .. more bromance please!!! :)) I love their bromance in episode 6! Ughh they are so cute!!

Also! I love the chemistry between Sun Jae and Shin Jae Yi! Idk why but I just love them together! I love the scene where GwangHo tease SunJae about Jae Yi! HAHAHAHA! Funny GwangHo eavesdropping and cute SunJae smiling! SunJae is really into JaeYi! Aigoooo!

I also smell something fishy about the forensic guy. I think he knows something or he is connected with what is happening with GwangHo. What if he is the killer? Or ...... idk! All I know is there is something about him... or he knows something.

Cha Hak Yeon!! :( So sad about what happened to him. But I think the reason he is killed is because he witness something connected w/ the case ........i don't know i'm just guessing. Can't wait to know more clues until we find the real reason behind it.

Danniah. Apr 10 2017 6:34 am This drama is another gem in 2017. Tbh, the first 2 eps were not that great because of its slow pace and everything about the background. But, after those 2 eps, the story is running faster and faster. It becomes more suspense and thrilling. The drama gives the familiar vibe we can only get in good criminal movies. Tho the first 2 eps were boring, in later eps, there are much things that make me come back again to ep 1-2 to see the connection between the cases and the background story.

As a fan of Korea criminal dramas, I can guarantee that OCN os the best channel for this kind of story. I can see why people try to compare this drama with Gapdong and Signal, but believe me, each drama is different. The only thing that similar is they took Hwaseong Case as their background.

You know, there are tens movies about Jesus out there but you don't say they were copying each other, right?

Nugrah Apr 10 2017 5:36 am The best drama, Must watch, cant wait next episode

Easter Lily Apr 10 2017 2:14 am This drama is nothing like Signal except in the use of the Hwaseong murders. If anything it's more like the British drama, Life on Mars.

If you like a good procedural, give this one a try. You may be pleasantly surprised. Terrific show with plenty of buddy cop humour.

Jennie Kim Apr 09 2017 10:44 pm It's not a copy of SignalN. Tunnel only has the same case (Miryang gang rape) and for those who didn't know, it happened in real life.

northerngirl Apr 09 2017 9:01 pm Entertaining and suspenseful...not a knock off of Signal (which I really enjoyed as well). Great cast ensemble. Acting is great. Plot keeps me engaged for the whole hour...

Syahrul Apr 09 2017 4:48 pm OCN never disapointed me... really great chemistry between the actors and great plot too...

winna_eka Apr 09 2017 7:41 am must watch drama

this drama so much fun im signal fan esp Lee Jaehan (cho jin woong) but if you think this drama copy signal you are wrong

tunnel have sama case with signal ... as long as gapdong (lee joon) drama

danu Apr 08 2017 6:58 pm Is any body realise this movie plot so similar with detective conan? Especialy ep 5, love it

Gantlion Apr 08 2017 1:36 pm This drama is cringeworthy and a copy of signal! no sense of origninality here.

libi Apr 07 2017 4:53 pm Hakyeon oppa hwaitiiinggggggg... !!!!! Starlight here to support u ? I love this drama

sammie92 Apr 07 2017 3:10 pm I love dramas like this. somewhat based on true cases but fictionalised, mixed with time travel, and an intriguing complex storyline that makes you wonder.

Park Gwang-Ho is a dectective that has worked as a homicide dectective for 10 years. while working on a serial murder case in 1985, looking for awnsers and chasing the murderer in the tunnel where the sixth murder acurd (Criminals come back to their crime scenes) he gets struk on the head by the muderer and is uncontious, when he wakes up in the tunnel and leaves it, he finds himself in 2016. Serial Murder case. 1. First murder: Victem Lee Jung Sook is in her twenties, was found in November 1985 at Soojeong-ri Bangjoo Road. 2. Second murder: victem Kim Kyung Seon is in her twenties, was found in November 1985 not twee weeks apart from the first murder, at Haein River. 3.Thirt murder: victem Oh Choon Hee is in her twenties, was found in Early December 1985 at a Reed Field near Mount Sungyoo. 4.Fourth murder: Seo Yi Soo is in her twenties, was found in March 1986 at Back Alleyway of Devision 18 (army base) 5.Fifth Victem: Was not known in 1986, Victem Kim Young Ja none as Kim Jung Hye in 2016 was a surviver of the serial murderer back in 1986, she never reported the crime, but most likely the incident accurt between March and December at Hwayang Road near Hwayang Woman University where she went to school at that time. Kim Jung Hye was found murderd in 2016 by another murderer. 6. Sixth Murder: victem Jin Seon Mi in her twenties, was found in December 1986 at Hwayang-ri Tunnel. 7.Seventh Murder: We don't know yet, we will find out in Episode 5. Notes: Park Gwang Ho Meets Shin Yeon-Seok on a blind date while working on a serial murder case, They get Married late 1985. After Park Gwang Ho disapears late 1986, Shin Yeon-Seok finds out that she pregnant (girl or boy) not known. Shin Yeon-Seok's Birthday is Januari 3rd, Park Gwang Ho planned to take Yeon-Seok on a cruis at han river as a birthday precent. (He coulden't keep his promis because he disapeard) Yeon-Seok did buy the tickets and waited. After Park Gwang Ho disape ard, Shin Yeon-Seok disapeard (it's not none what happend to her) Her person files disapeard. She could be death, or another victem not yet found. I have a bad feeling this is the case, we will know if a victem with Park Gwang Ho's whissel is found, Yeon-Seok did find the whissel she gave him in the tunnel, I think she would keep it close to her. The thirt victem was a none friend Oh Choon Hee, the girl Park Gwang Ho discribed as a sister to Shin Yeon-Seok. The fourth victem Seo Yi Soo was a newlywedded woman who just moved into burin apartment and had a child Kim Sun-Jae, Park Gwang Ho held the child while working on the case. Park Gwang Ho and young Jeon Sung-Sik looks around Soojeong-ri because he believes the murderer is from that neiborhood, there he find out about dogs disapearing and finds the stolen dogs death and burried in the garden of a male high school student (Jung Ho Young) Park Gwang Ho believes that Jung Ho Young is the Serial murderer and pregtisted on dogs first. the young, Jung Ho Young was taken for questioning in 1886, and released by the Chief at that time because had an alibi for the time of the murder, but the weird thing about it is that he did not get punished for the crime of stealing and killing dogs.. very suspicious. Jung Ho Young is None as a serial killer in 2016, but not none for how many young girls he acctualy killed. Jung Ho Young is the killer that slipped away both in 1986 and 2016, Lieutenant Kim Sun-Jae worked at the annam police station before, he made a mistake on a case involving Jung Ho Young where his partner at that time let Jung Ho Young go, now he snoops around other police stations whenever young girls get murderd.

Park Gwang Ho in 2016 After leaving Hwayang-ri Tunnel, he finds himself in 2016. 1. Park Gwang Ho ia almost run over by Young Park Gwang Ho (licensplate 24디9874) who is suposed to be a police transfer at Hwayang Police station, but went missing that night while being chased by the murderer(licensplate 70무6002). Young Park Gwang Ho could be the son of Park Gwang Ho because they share the same name and job, and babies take the surname of the fathers if not the full names, but surenames are commen in korea. so it makes you wonder. 2.Baby all grown up and a dectective at Hwayang Police station, Kim Sun-Jae once hold as a baby in Park Gwang Ho's arms will now be his partner. 3. An old friend and college from 1985 that meet again in 2016, Jeon Sung-Sik who now is Chief at Hwayang police station and who is Park Gwang Ho's boss at this time. (The young Jeon Sung-Sik once told Park Gwang Ho.. my dream is to become chief, Gwang Ho awnserd in your dreams punk, if you become the chief, then i'll be your son) 4. Professor of Criminal Psychology Shin Jae-Yi who could be Park Gwang Ho's daughter because she shares the same surename as his Wife Shin Yeon-Sook, but same surenames are commen in korea.so it makes you wonder. Shin Jae-Yi was adobted at age 6, and witnessed her adobted parents die in a fire, she was young and scared and did not know what to do, so she watched the wole thing which let to rumors about her setting the fire and killing her parents just because she watched it happen.

L Apr 06 2017 10:24 am The killer is the forensic scientist

chrysant Apr 05 2017 9:01 am I like this kind of drama. At first it feels similar with signal and gapdong(because of timeslip, and for the case) but later it goes to another good route. I like this. The plot, cast, everything. So far it's a good drama.

Ero Apr 05 2017 7:01 am I think the killer is a taxi driver who also a journalist in the past.

yanyanpark Apr 04 2017 1:29 am I love this kind of drama - solving cases, catching the culprit and how they gathered evidences. And at the end, it is either one of the detectives/police officers or one of the higher ranks is the suspect. I salute all the people behind Korean dramas. Every drama has its own unique plot that viewers love to speculate. Thumbs up to all of you! :) In pursuit of the culprit, Park Kwang-Ho traveled 30 years to the present. The culprit knew the mystery of the Tunnel that's why they can't catch him. He's traveling back and forth through time committing crimes, killing women. I just don't get it, why did he kill those women in skirts using a stocking and leaving a mark of his killings? How twisted a serial killer mind can be? Looking forward to this drama! Fighting! ^^

Uthie Apr 03 2017 11:41 pm I like this drama, why? 1. Im wondering who is the serial killer 2. All the detective hv their own chemistry, so fun but can be serious too, so they are still can catch the criminals 3. Even they're casing the serial killer as a line, but every series hv different story, so im not get boring at all 4. The mistery of tunnel itself, detective park past and present and his wife. 5. Hate and love detective park and detective kim, i wish someday i can see detective kim smile to park, he5.

J3anni3 Apr 03 2017 11:27 pm I think that there's a possibility that Shin Jae Yi is his daughter. She has the same last name as his wife. Young Park Gwang Ho can't really be his son because he was born in 1988 and his wife found out that she was pregnant after his disappearance at the end of 1986.

LoneGunMan Apr 03 2017 11:00 pm I agree with you LMAO, wholeheartedly. For the plot, I think the wounded kid being hunted in the forest is Park Gwang-Ho's kid and his purpose is to save the kid. But then again I may be wrong!!

Lauz Apr 03 2017 12:26 pm Overrated drama.

YoonBake Apr 03 2017 4:16 am Addition of previous comment: i think jung ho young(the serial murderer) was the high school boys that killed many dogs in the past that got caught by park kwang ho

YoonBake Apr 03 2017 2:51 am And i think the reason kim sunjae pursuit him because he thought jung ho young was the killer of her mother as park kwang ho suspected him to be the killer of the women in 1985

YoonBake Apr 03 2017 2:30 am @kat and the high school student that killed many dogs in the past become serial killer now(jung ho young)

AFN Apr 02 2017 11:22 pm @Kat I thought it was made clear that Jae-yi (Yoo-young's character) was adopted, and then the adoptive parents died. It's either that, or her mom remarried and went abroad.

The 1988 Park Gwang-ho is probably an eyewitness of a terrible event involving people in the higher-ups.

Taehyung_queen Apr 02 2017 7:42 pm @kat i agree with u part that Hyun min is son of the victim in 1986

Kat Apr 02 2017 6:57 pm Done watching episode 4 and I love it so far! At first I really don't like Lee Yoo Young coz she's so weird but after watching episode 4. I like her already! I think Yoon Hyun Min is into her! Omggg I want them to be together. I just hope that the writers will not make a love triangle between Yoon Hyun Min, Lee Yoo Young and Choi Jin Hyuk! I really want Choi Jin Hyuk to stick to his wife (eventhough I still have no idea what happened to her). I'm really curious to N's character here which is the other Park Gwang Ho. At first I though he might be Jin Hyuk's son but since other people say that Jin Hyuk's child is a daughter based on Press Release and Summary of the show. So I also thought that Yoo Young might be Jin Hyuk's daughter? But in episode 4, Yoo Young said that she saw her parents died. So? It means she grew up with her mother and father unless Jin Hyuk's wife (Yeon Sook) got married? But I doubt it. Or unless she's adopted?? Aahhh my mind is gonna explode! I really love shows like this that makes me guessing! I somehow feel like I'm a detective! Haha Also! I realize that Hyun Min is the son of the victim in 1986, the child whom Jin Hyuk carries in episode 1!! Omggg! This is so interesting! So Hyun Min's father in the drama is still alive? What if Hyun Min's father and Jin Hyuk met? Maybe he will recognized him in the past! Omggg! Can't wait for the next episode!! So exciting!! I love this drama! I also love Voice, Whisper, Signal, Gap Dong, Nine: Nine Times Travel, I Remember You etc!

kk Apr 02 2017 3:02 pm Professor Shin Jae Yi must be Park Kwang Ho's daughter. She has the same last name as his wife...Read somewhere that he traveled to 2017 to save his daughter. Such a great drama!!!!

fans yo! Apr 02 2017 8:52 am Wow. At first I watched this drama by accident. But it turned out so good for now! It has the signal's vibe but well it's ok for me. Good job for Choi Jin Hyuk, Yoon Hyun Min, and Lee Yoo Young

Ero Apr 01 2017 11:08 pm Im so into this kind of drama. And this one is good. Well, not as good as signal but it's worth to watch. I don't think it's a a copy of Signal. Yeah it has a similiarity but also different in many ways. So i'll keep watching and loving it

Flustered Apr 01 2017 8:45 pm I don't like this type of drama. It took 16 episodes just for the police to catch a serial killer. You can bet the police actions will be stupid and dumb for 15 episodes and will finally catch the killer by a stroke of luck at episode 16. By which time, the serial would have killed have of Seoul. Even with the ability to travel through time, it took the police 30 years and 16 episodes to catch a single killer!

jinjoo Mar 31 2017 9:27 am just started watching this & it's quite interesting! like one of u said here it's that baby who lost his mother & now the Lt. in this station, kinda baffling though that he may hv died in that tunnel, i wonder what happen to his wife who was also pregnant at the time he disappeared! am watching this bc of Choi jin hyuk after i just watched him in Pride & Prejudice, he's quite a good actor but i think he's under-rated! am also watching him in Emergency Couple while waiting for the eng subs! nice drama!

deiideis Mar 30 2017 10:00 pm Kim SunJae (Yoon Hyun Min) is that baby right? the son of the fourth victim in 1986. How funny if Park Gwangho realized that his partner was the child he always carry. They now behave like Tom and Jerry^^

Rhara Mar 30 2017 8:24 pm Voice, defendant, whisper and then Tunnel are korean dramas I'm watching in 2017. I think thriller be my favorite one in this year. Watching this drama is the best one to spend your time during weekend. ^^

Trine Mar 30 2017 2:09 pm I really really love this drama!! :D :D

Bunny Mar 30 2017 2:55 am It was really funny to hear bts :))))

Lucky Mar 29 2017 11:17 am I think the writer fan of bts (:

Beverly Mar 28 2017 10:58 pm This is starting off pretty well, I loved Signal and this is similar.

Aswer Mar 28 2017 1:02 pm Don't like the detectives in this drama... they're so dumb lol

Xsara Mar 28 2017 12:54 pm Wtf this is a copy of Signal... sorry but this drama will never be as good as Signal....... terrible.

northerngirl Mar 28 2017 9:27 am Did not want to watch another crime drama after the great Defendant, but this one is too good pass up! After two episodes...two thumbs up!!

lehmx Mar 28 2017 3:11 am I think that Shin Jae Yi is his daughter. But I really wonder where Shin Yeon Sook is in the future. Is she dead ? Or perhaps she is living in a foreign country.

Fleur Mar 28 2017 2:42 am Mh Shin Jae-Yi could be Park Gwang-Ho's daughter? I mean if Yeon-Sook gave birth while he disappeared, he wouldn't have been here to recognize her, so she could have taken her mother's maiden name. (not sure how it works in South Korea tho)

suissant Mar 27 2017 4:18 pm @tirashine It's impossible they are father and son. According to the press release and summary of the show he has a daughter not a son.

tirashine Mar 27 2017 6:30 am After watching two episodes so far so good, I love this drama. Drama Filled enigmatic, hard to guess! It looks like what happened in 1986 and 2017 are closely related. I think Cha Hak Yeon (Park Gwang Ho) and Choi Jin Hyuk (Park Gwang Ho) is the Father and the Son, even the name of their profession are very similar, as there is a possibility. But thinking back again Cha Ha kyeon (Park Gwang Ho) was born in 1988 while Shin Yeon Sook then pregnant in 1986 when Choi Jin Hyuk (Park Gwang Ho) should dissipate, his son was born in 1987 instead of 1988? It's full of mystery.

KwangHo Mar 26 2017 10:53 pm For those who are confused, the first story was kwang ho time travels to save his daughter but in here now we've seen in the first two episode is different with the first plot because I think the first plot of the story is rewritten but I don't know the reason but another information is the director of this drama was changed that's why I think its one of the factor why the first plot was change into this one now that he(Park Gwang-Ho) has no daughter but he has a wife and he just accidentally brought into the future because he was chasing the culprit and in 2016, the murder case incident that happens in 1986 is resuming after Gwang Ho got time-slipped into 2016.

lovemesomedramas Mar 26 2017 4:54 pm I watched the first episode and loved it! It's intense already and the whole time traveling aspect is interesting. I'm curious to see how this will unfold. Fighting!

Nugrah Mar 26 2017 6:18 am I like Shin Yeon-Sook......

gaya Mar 26 2017 6:02 am Is that guy seo in guk? looks like him tho

NGS Mar 26 2017 4:50 am just realized that Cha Haekyeon's role name also Park Gwang Ho???

Dana Mar 26 2017 2:58 am @lovedramas I've been into the Hwaseong case for years and I know every detail of it, so I can tell u that yes indeed the first episode was about that. I checked the French/british drama u said it was based on and in no episode i found exact same murder so...? I once again think this drama is based on real cases from Korea. Hwaseong murders started in 1986 okay, one year up and down, no one cares but the way he kills, the stockings, the location is exactly the same. Once again I'm talking about the murders not the overall drama.

MissCharisma Mar 25 2017 9:54 pm is that N???? Omo!!! have to watch for sure! ^_^

via Mar 25 2017 7:40 pm yeay finally its airing!

Nici Mar 18 2017 10:43 am Bring back Cha Hak Yeon because he will still be a cast in this drama haha thank you

Ricky Mar 14 2017 11:13 pm I cannot wait for this ?

Fleur Mar 13 2017 9:31 am @lovedramas Actually, Tunnel (and the US The Border) is remake of the swedish-danish serie Bron. Those three series have nothing to do with the korean Tunnel which has a strong science-fiction vibes. It looks more like opposite of the british series Ashes to Ashes & Life on Mars where a cop from the present is propulsed in the past. By the way, I'm excited so far by this drama. It looks promising!

lovedramas Mar 05 2017 11:34 am @bittersquash It's not about a gyeonggi case. Tunnel is a French series with clemence poésy (Harry potter) broadcasted in 2013.

bittersquash Mar 05 2017 4:39 am Is this about gyeonggi case again? After Gap dong, signal, and now tunnel? hahahahahaha
