South Korean crime thriller based on real events. In a small town outside Seoul, over the course of six years between 1986 and 1991, ten women were brutally raped and murdered within a 2-kilometre radius. The killer was indiscriminate in selecting his targets: the victims ranged from a 71-year-old grandmother to a 13-year-old schoolgirl. As time went on, the methods of the killer became bolder and more well-planned. Other than the victims, he left not a shred of evidence. Despite a police investigation involving over 300, 000 police officers and the interrogation of over 3, 000 suspects, no one was ever indicted for the crimes. The film, which has been compared to 'Silence of the Lambs' and 'Seven' for its powerful and unflinching depiction of a serial killer, has also been seen as a scathing political allegory for the state of Korea itself.
