: Detective Keiko Kirishima (Japanese pop singer Hitomi in her thesping debut) is a determined young woman whose interest in detective work has inspired a downward career switch from academic criminology to homicide fieldwork. When a spate of suicide cases occur involving victims slashing themselves with razors in their sleep, Kirishima is ordered by her superiors to take a parapsychological approach.
The link between the somnambulistic suicides is that they all have called the same mobile phone number immediately before their self-inflicted deaths. Through a police colleague, Kirishima learns of Kagenuma's unusual talents and attempts to enlist his assistancebut Kagenuma turns her down. To force Kagenuma's hand, Kirishima calls the killer's number herself, putting her own life in jeopardy, so that they can, if need be, both face death together.
