Cure

(1997) A wave of gruesome murders sweeps Tokyo, and the only link is a bloody X carved into the victims' necks. In each case, the murderer is found nearby and recalls nothing of the crime. Detective Takabe and psychologist Sakuma are called in to figure out the connection, but their investigation goes nowhere. An odd young man, arrested near the latest murder, has a strange effect on everyone with whom he comes into contact. Takabe starts a series of interrogations to determine the man's connection with the killings.
