In his past, Nam Gi-Jun (So Ji-Sub) was a member of the Bongsan Gang that was led by Gu Bong-San (Ahn Kil-Kang). Nam Gi-Jun defeated other gangs through violent battles and the gang grew into a large company, but Nam Gi-Jun decided to leave the gang. His younger brother Nam Gi-Seok (Lee Jun-Hyuk) joined the Joowoon Gang that was led by Lee Ju-Woon (Heo Jun-Ho). The two gangs were rivals. For his brother, Nam Gi-Jun quit the Bongsan Gang by cutting his left Achilles tendon.

11 years later, Nam Gi-Jun lives peacefully and makes a living by suppling drinks to businesses run by Bongsan. His brother Nam Gi-Seok is now the second highest ranked person in Joowoon, but he suddenly dies. In order to reveal the secret behind Nam Gi-Seok’s death and take revenge on those responsible, Nam Gi-Jun goes back to the gang world that he left behind 11 years ago.

Bea Dec 17 2025 12:05 pm I'm so the glad that i watched this. The reviews aint lying. This is really one of my best watch this year. Stellar cast and acting! Do i also have to mention the action scenes? So freaking cool!. Actually, I recently noticed a shift in kdrama from long series to short series. And, i'm loving korean mini series so far, those i've watched are definitely plot packed, and has better pace and storyline than 16-episode kdramas. Mercy for None just easily became one of my faves so far in my list.

Trauma Code Family Matters Mercy For None SLine Karma Queen Woo Kingdom

Sheila Dec 12 2025 9:30 pm Excellent!!! Watching this show was like watching John Wick. Loved it !

TJ Dec 01 2025 4:33 am The fight scenes became repetitive, and the ending was a depressing fizzle-out.

Nenny Sep 08 2025 12:30 pm I loved it so muchh!!

John paul Aug 23 2025 11:05 pm Literal korean John Wick drama

Ms. Gerbera Aug 08 2025 5:58 pm Cheon Hae beom so hooot! So many good looking gangsters in this kdrama goshh

Jajang Aug 08 2025 5:55 pm I love it so much!!

Nik Aug 01 2025 5:41 pm A bloody revenge action drama at its best! Top cast wherever you look! I didn't see any flaw, there's perfect tempo and scene mix

Chamonks Jul 29 2025 12:30 am I rarely watch dramas with excessive violence, but I braced myself because of Seo Ji-sub. His previous drama was such a disappointment, but I knew he would nail his character on this one. And witnessing both him and Cha Seung Won in one frame is just amazing.

Laura Jul 25 2025 2:39 pm Really a great drama with unique plot great acting. All did their role so perfectly ,they are llittlerally living in the role.

Mao Jul 15 2025 12:02 pm Thank you for bringing together all of these amazing actors into one series. I watched it until 3am, because I couldn't dare sleep without finishing it.

Jillibean Jul 03 2025 5:18 pm Excellent cast. Would love my top favorite Korean actor So Ji Sub to play in a romantic comedy next. He hasn't done one for a long time. Too long.

Zeus Jun 30 2025 5:00 pm Brilliant drama!! SJS is top as always, never disappoints with his superb acting! For me 10+++++

Drei Jun 28 2025 5:44 pm I watched this for Young Woo, I just clicked it without knowing how star-studded and high quality this kdrama is its like watching a long action movie. Not my usual kdrama but damn the acting and action scenes were top tier. More projects like this for Young Woo he did such a good job in his character ? Also, it is too gory but nonetheless its a 10/10 for me!!!

Firestone Jun 26 2025 1:54 pm Great actor! So Ji Sub! Super good looking too! This is full of action which is great! But too much profanity! Don’t care for translation

5_ooo Jun 26 2025 10:48 am One of the best k-dramas released in 2025. absolute class. all of the actors are superb and spectacular at their roles. especially So Ji-Sub and Lee Jun-Hyuk... their eyes hold such emotion...

also make sure to watch this with both earphones in, it heightens the watch experience.

Ariff Jun 22 2025 9:44 am It’s been long time I don’t see any k-dramas. But this is something you should choose on your weekend. Only few episodes. Wish it had 16 episodes like old kdrama concept. 11/10

Action Lover Jun 21 2025 3:07 pm This was brilliant! So much action and revenge, and everything tied together nicely! 8.5/10 must watch :)!

jae Jun 18 2025 7:41 am first i thought it was all like the Movie John Wick but i was wrong , when Gi Hun done killing Gu jun Mo , and i was mind blown that all this time the son of Lee Ju was all behind of it

Marjory Jun 18 2025 5:35 am And to think I just finished watching John Wick 4 yesterday. This series was a whole lot of fun and rollercoaster rides. Although I must say, around episode 3, you already knew who the culprit is. Lee Jun Hyuk and So Ji Sub really have superb fighting performances. Plus tall actors really are so cool in action series

EMMR Jun 16 2025 11:21 pm All I got to say is, "If you love John Wick and a fan of Kdramas, you must not miss watching this." To describe this series in 2 words: Maximum Aura

Code6757 Jun 14 2025 1:33 pm who is the actor who plated Kyota (Yakuza gang member) in EP.1?

Rad Jun 12 2025 10:19 am I enjoyed watching this series! Good action packed.. Fast paced and no boring episodes.

chow Jun 11 2025 9:42 pm Noooo! bring back my Gi Seok!!!

Sudip Jun 11 2025 12:02 pm The drama is mediocre.ending is weak.Cha Yeong-Do was unnecessary.Kim Chun-Seok and Cheon Hae-Beom they should be given more significance.

Lala Jun 11 2025 12:27 am Nam Gi Seok was so good, sadly he died early for the story plot ?

Santosh Raut Jun 10 2025 2:08 pm Don't compare with John Wick :) This drama also features suspense and thriller elements.

Nadine Jun 08 2025 7:13 pm Well, I guess the all planet was watching the drama same time as me because I have been ejected more than 10 times out of Netflix, this was rather a bloody drama that I could not stop watching. A little confusing though with all these different parties involved. Pity that Lee Jun Hyuk had not more screen time of course. All of the actors were super great and Si ji Sub was incredible. Bravo

happy98 Jun 08 2025 6:53 pm I was rewatch John Wick 1 before starting this drama, I found sooo many similarities. But this action drama feels better, because GiJun fights with bare hand and not extremely neat like Wick, better emotional shoots of every roles. 8.7/10 noir genre ╮(╯▽╰)╭

Yang Jun 08 2025 9:16 am Been waiting for this drama and it never disappoint!! i so love the action scenes, it's kinda brutal but jisub nailed it as expected. What a nice comeback for him. I love this kind of drama just pure agony no romance included.

Dreamhigh Jun 08 2025 9:00 am I love this drama, SJS is never failed his action, so good to see him back

Renji Jun 08 2025 7:36 am I see a heavy reference to John Wick. Just replace the dog with the protagonist's brother.

Phoebe Jun 08 2025 6:51 am I must say is always good to watch old actor more then young because they still have in them.

Sushi87 Jun 08 2025 5:09 am Great casting! So Ji Sun is so handsome here.

mt Jun 08 2025 4:00 am The show is 6.5/10 for me... Action scenes are good.. love that there is no draggy romance parts to slow down the drama.. its just go go go...

But I do have big grouse... they made ML too superhuman. when he gets stabbed or shot... he continues, but for others.. a single stab and they die... let's at least be real a little..

Kimmie NC Jun 07 2025 11:28 pm Yessssssss! This was awesome. Fast paced. Got to the point. Full of action! Great acting from the entire cast.

MiRafa Jun 07 2025 10:02 pm This is whats story of revenge should be.. less talk.. action 100/100.. fast paced... kudos!

SueS78 Jun 07 2025 7:26 pm Exceptional casting. Exceptional acting. Exceptional storyline. Overall, 100%. Love it! Big So Ji-Sub fan since the 2000s, every drama, every movie I’ve watch. This is what I remember him as, an action actor. Love it!

Ani Jun 07 2025 3:45 pm Great series! Just binged watched it.

Chey Jun 07 2025 2:41 pm Loved, loved, loved it!!!!

So Ji Sub nailed this and the whole cast!? 10/10. No need for romance. I really wonder how much was the budget for this serie. Amazing Testosterone overload!

Mamaliciouslips Jun 07 2025 3:41 am Best come back for So Ji Sub! Loving it!

Jane Jun 06 2025 3:49 pm its John Wick X New World X A man from Nowhere X Physical 100... hahaha

Badoodles Jun 06 2025 2:52 pm The story is like John Wick X New World (Lee Jung Jae, Hwang Jung Min Movie)

Bhurgs Jun 06 2025 1:48 pm Just finish the whole episode.. i know the story line is common but for me I love it. Unpredictable and every episode is pack of action.. SJS is always Awesome in action.. all the characters are great.. 10/10

M Jun 06 2025 12:16 pm Wondering how big the budget is? Coz like the familiar actors’ faces in the series are kinda not cheap omg. Amazing cinematography, fighting scenes and bgm. 10/10

man Jun 06 2025 10:51 am This drama literally copy paste of John Wick

Your 112 Jun 06 2025 10:08 am I love this drama. the legendary characters in this drama story are very much in line with the plot of the story, the extraordinary performance of the cast. thank you director, story writer, and all the team in the drama Mercy for None. can't wait for other works !!!!

ivy Jun 06 2025 9:30 am so so so great ! i’m in aweeeee !!!!!!!
