Le leonesse (1971)

It's the story of a conflict between a mother, Christine, still very beautiful, and her daughter, Clara. The other characters are Luis, who enjoys love, Patrice, who discovers passion, and Stevens, a young hippie who breaks into the villa and for whom only the sexual act counts. Gathered near a small beach during a vacation weekend, these people will tear each other apart, truly "possessed" by their desires and passions.
