When serial killer Kyung-chol kills the pregnant fiancée of secret agent Soo-hyun, the agent swears to avenge her death. He soon tracks Kyung-chol down, but not to deliver him to justice. Instead, he has entirely different plans for the vicious killer.
Jae-woon Kim, one of most prominent Soth Korean directors, made a name for himself early in his career with films such as horror A Tale of Two Sisters, crime thriller A Bittersweet Life and comedy The Good, the Bad and the Weird. But no one was prepared for the shock he delivered with this incredibly cruel and violent thriller that keeps pushing the genre boundaries and often goes over the edge of horror. It also offers astonishing performances by Byung-hun Lee (The Good, the Bad and the Weird) and Min-sik Choi (Oldboy).
