The beautiful Countess Martine de Bressac is released from the expensive asylum where she was incarcerated after castrating her former lover. She returns to her luxurious villa on the coast and goes at once down into her private underground dungeon. It's here that she indulges herself in the perverse sexual practices that give her life meaning, surrounded by the bizarre human statues of her previous victims. Her husband, Charles, feeds his wife's sick fantasies, aware that she is his meal ticket to a life of luxury. He announces that he has a new game for her - they will befriend and seduce the young and virginal daughter of a rich neighbor. But things do not go exactly as planned.
