When the jealous Matteo finds some pictures and letters from her former lover Bernard in Venice, he hangs up the phone and the upset and amoral Carla has a brief affair with Moira and intercourse with an acquaintance in a party. When Matteo comes to London, he concludes that his lust for Carla is more important than his jealousy and her behavior.
While scouting out apartments in London for her Venetian boyfriend, Carla rents an apartment that overlooks the Thames. There she meet the lesbian hyper-horny real estate agent Moira.
