Kim Soo-hyun (Lee Byung-hun), a young police officer working for the National Intelligence Service, is about to marry his beloved girl, Joo-yeon. However, on a snowy night, Joo-yeon, who was driving home alone at night, was brutally murdered and dismembered. Soo-hyun was in agony. He found photos of four main suspects and began to track down the murderer independently. After some investigation, he finally targeted a middle-aged uncle named Jang Kyung-chul (Choi Min-sik) who chartered a car for a certain college. Jang had a rough life and a very twisted personality. He often attacked women returning home at night and killed them mercilessly. Soo-hyun found Jang's base and punished him cruelly, but he finally showed mercy. Jang, who was lucky enough to survive, instead aroused all his beastly nature. A Shura battle between beasts gradually became fierce... Some of the scenes in this film were too bloody and became the first commercial film in South Korea to be restricted for release.
