A wave of gruesome murders is sweeping Tokyo. The only connection is a
bloody "X" carved into the neck of each of the victims. In each case the
murderer is found near the victim and remembers nothing of the crime.
Detective Takabe and psychiatrist Sakuma are called in to figure out the
connection but their investigation goes nowhere. An odd, young man is
arrested near the scene of the latest murder, who has a strange effect on
everyone who comes into contact with him. Detective Takabe starts a series
of interrogations to determine the man's connection with the killings.
