Japanese horror directed by Kiyoshi Kurosawa. A series of murders have been committed across Tokyo, with a distinguishing mark that connects them: a bloody 'x' carved into the neck of each victim. In each case the murderer is found near the scene of the crime, but has no memory of committing it. These 'murderers' turn out to be ordinary citizens who all claim they had no control over their actions, and have each had previous interactions with the same mysterious man. But who is he, and what is this power that he seems to wield over others? Detective Kenichi Takabe (Koji Yakusho) must now place his own sanity on the line in an attempt to end the wave of inexplicable terror sweeping the city.
