Plaisir à Trois plot
Martine Bressac is discharged from a psychiatric clinic after a year of treatment and driven home by her chauffeur Mathias. She is greeted by the demented hunchback gardener Malou and the deaf-mute maid Adèle, and impatiently demands the key to her mysterious private room. There, like exhibits in a waxwork, lie the bodies of beautiful girls frozen in terror-like poses on the verge of death. With Mathias' help, Martine has just added another girl, a prostitute, to her collection when her husband and accomplice, Charles, returns home with slides of another future victim: Cécile, the virginal daughter of a diplomat.
