While he seems ordinary at first glance, Iwao Enokizu (Ken Ogata) is actually a violent murderer running from police. Leaving behind his wife (Mitsuko Baishô), he hides out with Kazuko Enokizo (Mayumi Ogawa), a brothel owner who desperately loves him but does not know he is a killer. Iwao does not understand his urge to kill, but he knows that his terrible deeds have burdened both his wife and his father (Rentarô Mikuni) and fears his relationship with Kazuko cannot last.
