Nijima, a white-collar worker, finds the man responsible for his young daughter's murder. He tortures and interrogates the man, who maintains his innocence, before killing and burying him. He returns to his ordinary life feeling listless and hollow, until he encounters a man that introduces himself as an old friend. The man offers Nijima a new job, and subsequently introduces Nijima to his band of hired killers.
