While investigating the gruesome death of a woman found in a puddle with her stomach inexplicably full of seawater, Detective Yoshioka begins to wonder whether he himself is actually the killer he's been looking for. He doesn't remember committing the crime, but the murder scene is littered with his belongings -- and his fingerprints are all over the body. Kiyoshi Kurosawa directs this gritty horror tale from the producers of The Grudge.
