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, investigative methods are suspicious, and forensic technology is near non-existent. Park claims to be able to find 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's partner Cho beats Baek, forcing him to confess.
