In Japan, a man (Masao Inoue) takes a job as a janitor at a mental asylum in order to be near his wife (Yoshie Nakagawa). Although his wife suffers genuine mental anguish, the man believes he can rescue her -- but his attempt to break her out one night backfires when she panics. After she returns to her room, the husband again makes plans to try to take her out, only to be interrupted in the attempt by a doctor and several attendants, whom he attacks and believes he has killed.
