I Saw the Devil

“Abandon all compassion.”

Kim Soo-hyeon (Lee Byung-hun), a secret agent, wants one thing after his fiancée is murdered: to find the man who did it and make him pay in person. That man is Kyung-chul (Choi Min-sik), a killer who takes his victims for pleasure. Kim Jee-woon follows Soo-hyeon as he sets out to hurt Kyung-chul by whatever means it takes, even if he has to become a monster himself.
