Memories of Murder is a 2003 South Korean crime thriller film co-written and directed by Bong Joon-ho. It is loosely based on the true story of Korea's first confirmed serial murders, which took place between 1986 and 1991 in Hwaseong, Gyeonggi Province. Song Kang-ho and Kim Sang-kyung star as Detective Park and Detective Seo, respectively, two of the detectives trying to solve the crimes.

Plot

In October 1986, two women are found raped and murdered on the outskirts of a small town. Local detective Park Doo-man, not having dealt with such a serious case before, is overwhelmed—evidence is improperly collected, the police's investigative methods are suspicious, and their forensic technology is near non-existent. Park claims he has a way of determining suspects by eye contact. He questions a scarred mentally handicapped boy, Baek Kwang-ho, because he used to follow one of the victims around town. Park uses his eye contact method, thinking Baek is responsible, and has his partner Cho beat confessions out of Baek.
