I Saw the Devil

“Abandon all compassion.”

A National Intelligence Service agent (Lee Byung-hun) sees his fiancée murdered by a serial killer (Choi Min-sik) and decides to hunt him down himself. Instead of turning the killer over to the police, he wants to make him suffer as payment for what was taken. Kim Jee-woon tracks him deeper into a cycle of violence where the line between hunter and hunted dissolves, and vengeance becomes a trap that swallows everyone it touches.
