"The worst of them will stay with you... forever."
A sadistic serial rapist and murderer of young women terrorizes a small province in 1980s South Korea. To prevent further crimes, three increasingly desperate detectives with conflicting methods race against time to unravel the violent mind of the killer in a futile effort to solve the case.
