A young girl (Agostina Belli) marries a handsome and successful but brutish local butcher (Gianni Macchia) at the behest of her contessa stepmother. The new wife turns out to be frigid on their wedding night, and the couple have a big fight. The wife goes out of town to stay with her older, married sister (Ewa Aulin) and gets involved with her sister’s jaded swinger friends. The husband consoles himself by picking up prostitutes and carrying on with a sexy, voluptuous neighbor (Femi Benussi) right in his new mother-in-law’s villa. For some reason the mother-in-law considers this a turn-on and becomes sexually drawn to her loutish son-in-law.
