Nightmare Detective

In Tokyo, Detective Sekiya investigates the death of two suicides with Detective Wakamiya and the rookie Detective Keiko Kirishima. Both victims were stabbed while sleeping and the skeptical and experienced Sekiya concludes that they have committed suicide. However, Wakamiya discovers that both victims had dialed "0" on their cell-phones before their death and they recorded a weird message. The police officers believe that someone is inducing potential suicidal persons to kill themselves, but the chief of police decides to split the team and assigns Keiko to find a medium to help the police in the investigation. She meets Kyoichi Kagenuma, who is also a suicidal man with the ability to enter in the dreams, and tries to force the reluctant man to help her.
