Synopsis

Kyung-chul (Choi Min-Suk, Old Boy) is a dangerous psychopath who kills for pleasure. Soo-hyeon (Lee Byung-hun, Squid Game), a top-secret agent, decides to track down the murderer himself. He swears revenge on the bloodthirsty serial killer who slaughtered his fiancée, even if it means that he must become a monster himself. Unflinching and depraved, I Saw the Devil is a pulverising, operatic thriller propelled forward by fiery rage and top-notch filmmaking.
