In 1980s South Korea, a small village is shaken by a series of murders of young women that ignite fear and desperation within the community. Two detectives, Park Doo-man, an experienced but tough local cop, and Cho Yong-koo, a rookie with aspirations, are assigned to investigate these horrific crimes. With a more visceral than methodical approach, Park clings to the leads provided by his instinct, while Cho tries to follow the stipulated procedures and gather forensic evidence to ensure their progress.
As the investigations unfold, tensions between the two detectives grow. However, the lack of evidence and disorganization in the collection of clues make each step toward the truth increasingly frustrating. Although they begin to see patterns and similarities among the crimes, they feel powerless against the complexity of the case and the mounting pressure from public opinion.
Over time, the detectivesโ efforts are overshadowed by the inefficiency of the system and the technological limitations of the era, culminating in a heartbreaking and unexpected conclusion. With no definitive answers, this story reflects not only the struggle of the investigators but also offers a profound look at human nature, fear, and the impunity that often surrounds the crimes that leave scars on a society.
