I Saw The Devil
One night, a school-bus driver named Jang Kyung-chul encounters a pregnant woman named Jang Joo-yun, and offers to fix her flat tire. After beating her unconscious, Kyung-chul executes her with a makeshift guillotine at his home, and scatters the body-parts into a local stream. When a boy discovers one of Joo-yun’s ears, the police arrive en masse to conduct a search, led by Section Chief Oh and Squad Chief Jang, the latter being Joo-yun’s devastated father.
The victim’s fiance, Kim Soo-hyun, who is an agent of the National Intelligence Service, is also present and vows to take revenge against the murderer. Soo-hyun learns of the four suspects from Squad Chief Jang, and proceeds to privately torture and interrogate two of them. Upon searching the home of Kyung-chul, the third suspect, Soo-hyun finds Joo-yun’s engagement-ring, proving that Kyung-chul was the perpetrator.
