"A team of crime investigators headed by Kim Mi-yun (Uhm Jung-a) is summoned to a garbage dump, where a disgustingly mutilated body of a high school girl is discovered, along with a fetus removed from her body and deposited in a brown bag. Another pregnant woman is strangled to death in a bus, her belly cut open, spilling out a still-moving unborn child. They find that the modus operandi of these gruesome murders is an exact replica of the ones perpetrated in the past by the psychotic Shin Hyun (Jo Seung-woo), now a condemned inmate. The police naturally conclude that a copycat is carrying out these new murders. Detectives Kim and Kang (Chi Jin-hee), however, are convinced that Shin Hyun is somehow committing the murders without ever leaving his jail."
