Retribution

is a 2006 Japanese horror-mystery film directed by Kiyoshi Kurosawa, starring Kōji Yakusho, of a detective's investigation of serial murders that leads him to a mysterious woman in red who slowly draws him into the darkness. Plot Yoshioka, an experienced detective, investigates the murder of an unknown woman in a red dress. She was drowned on the Tokyo waterfront, but an autopsy reveals that her stomach is full of seawater. Moreover, all the clues he finds relate to himself: A button found at the murder scene matches one that is missing from his own coat, and fingerprints found match his own. Yoshioka realizes that the only viable suspect is himself; but he doesn't remember a thing. A ghost in a red dress soon starts appearing to him. As these apparitions become more intense and bizarre, similar murders occur with people killing loved ones for small infractions. All the perpetrators are found by Yoshioka as he searches for clues about the original murder. Eventually the drowned woman is identified. Yoshioka visits her parents, only to find she had a boyfriend who was extorting her parents, who happens to visit the house at the same time. He quickly confesses to the crime. Yoshioka is visited by the ghost again who reveals that she is not the murdered woman, but a ghost of a woman whom he saw in the window of an asylum fifteen years ago who has died. All of the murderers took the ferry past the same asylum. Yoshioka sends his girlfriend away, afraid of what he might do to her. He goes to the asylum, where the woman in red agrees to forgive him for not helping her 15 years ago. He goes home, only to discover that he murdered his girlfriend 6 months ago. Going insane, he tries to forget. He collects the bones, and goes to the asylum to pick up the ghost's bones. His partner arrives at his apartment and finds the empty bowl Yoshioka used to commit the murder. The ghost stalks him in the background. As an earthquake occurs, the bowl is now filled with water. The ghost suddenly appears above him and dives down dragging them both into the bowl. The film ends with Yoshioka walking in the street holding a bag containing his girlfriend's and the ghost's bones, with the ghost repeatedly saying: "I am dead. So please, I want everyone to die too".
