Lee Geum-Ja is forced to confess to a crime she didn't commit and she spends 13 years in prison where she fantasizes about unleashing her wrath on her wrong-doers after her release from prison.

7. Lee Byung-Hun In I Saw The Devil (2010)
I Saw the Devil, directed by Kim Jee-Woon, is not a movie for the faint-hearted. It is a blood-curdling tale of murder, pain, suffering, and revenge. Choi Min-sik plays the character of Kyung-Chul, who is a psychopath who kills for pleasure. Kyung-Chul is the embodiment of pure evil, and his lack of motive for murders makes the character even more spine-chilling to watch. The movie delivers a punch in the gut initially as he kills the fiancée of an elite secret agent, Kim Soo-Hyeon. A sinister game of cat and mouse with outbursts of graphic violence follows. In his hunt for Kyung-Chul, Kim Soo-Hyeon, played by Lee Byung-hun, is more than willing to blur the lines between good and evil. Lee Byung-hun's performance is grounded in reality and makes the audience root for him to get his revenge even through brutal methods. Kyung-Chul makes the viewer's skin crawl, and everyone wants him to die by the end of the movie as there is no redeemable quality about him. The film delves into human depravity as these two characters cross path with each other for the first time. Kim Soo-Hyeon beats Kyung-Chul to a pulp, instead of killing him. He decides to thrust a GPS tracker down his throat so that he is aware of his location all the time and can listen to his conversations. The emotional and mental breakdown of Kim Soo-Hyeon is hard to watch and hard not to sympathize with. Lee Byung-hun's portrayal is sad, vulnerable, unnerving, formidable yet understandable. I Saw the Devil becomes the embodiment of the phrase 'Revenge is a dish best served cold' as the movie reaches its conclusion. Lee Byung-hun won the Grand Prize in the 2011 Baeksang Arts Awards and was nominated in the category of 'Best Actor' in Grand Bell Awards ceremony and the Blue Dragon Film Awards ceremony.

9. Im Soo-Jung In A Tale Of Two Sisters (2003)

There awaits a shocking revelation in the end, which brings the story to a full circle. Im Soo-Jung delivered a phenomenal performance, which was critically acclaimed.

10. Bae Doo-Na In Kingdom (2019-Present)
The last entry on this list is a little different from the rest of its predecessors because it is a TV series that is still ongoing. It is Netflix's first original Korean series and follows the story of a prince who sets out on a quest to investigate the origin of a deadly plague that begins to ravage his kingdom. This TV series is a zombie horror wrapped in a package of period drama and delivers genuine scares. Bae Doo-na is a powerhouse of an actor, and her layered portrayal of Seo-bi steals the entire show. Seo-bi is a physician who joins forces with the country's crown prince to defeat both zombies and court corruption. Instead of being a submissive woman who is protected by men and gets easily scared of zombies, who would be more stereotypical of women of that time, Seo-bi is a brave, strong, and nurturing woman who can pulverize a zombie's head if required. She is a force to be reckoned with in horror drama.
