Marlène, a young woman who has just arrived in Paris, meets a boy with homosexual tendencies, who during their first night of love behaves in a sadistic way. At first shocked by this attitude, she took a liking to it very quickly. From then on, in all of her adventures, she will always go further into masochism, forcing her partners to endlessly mortify her, alone or in a group. A real madness has seized her, which will lead her to the most extreme perversions.

Amours Collectives starts out as libertarian porn, but ends up more like direct cinema, in which the film itself functions as its own making-of! Witty, salacious scenes follow one after another, with the director more or less becoming the central character.

An evil count lures beautiful women to his castle, there to imprison them in his torture chamber for his amusement.

Pierre has sexual fantasies about his next door neighbor Marianne leading his wife to get him an appointment with a sex therapist. Jean-Louis Vattier dreams about his lovely downstairs neighbor, Brigitte Lahaie, although his dreams occasionally turn into nightmares involving his hard hat co-worker Dominique Aveline. One particularly strange and violent sequence is not made any more watchable by some slow motion fighting accompanied by the usual ‘arousing’ sax music instead of more threatening music, but this entire film is one big incomprehensible trip anyway, so the viewer had better prepare for more far out scenes. Pierre awakes to find his beautiful blond wife (although she’s no Brigitte) played by Ursula White. Obviously their marriage is in trouble, with him living in a fantasy world of his own making while she, Janine, has taken a lover of the same sex (Liliane Lemieuvre as Rosette). Pierre spots Brigitte in a book store and begins to fantasize once more.

Therefore, she goes out searching, and finding, a number of liaisons with men and women alike. On one of her outings, she happens to see François having an affair with a man.
