I Saw the Devil

Abandon all compassion.

A brutal, morally corrosive revenge thriller that systematically dismantles the distinction between hunter and hunted, victim and perpetrator.

Kyung-chul is a dangerous psychopath who kills for pleasure. Soo-hyeon, a top-secret agent, decides to track down the murderer himself. He promises himself that he will do everything in his power to take vengeance against the killer, even if it means that he must become a monster himself.
