Alain Revent, a seductive and refined man, derives a peculiar satisfaction from debasing his wives. The first, driven to the brink of despair, throws herself out of a window. Enlisting the help of an equally perverse casual acquaintance, Dino, the "handsome brute" proceeds to emotionally torture his second wife, Nathalie. The sadistic plan is picked up on by Officer Leroy who suspects the truth. Will he be able to snatch the unfortunate woman from the evil Alain's clutches?
