A Tinto Brass triple bill. 'The Key' is set in 1940. A couple celebrate the 20th anniversary of their wedding, but neither of them is fully satisfied with the sexual side of their relationship. Nino (Frank Finlay) and Teresa Rolfe (Stefania Sandrelli) both keep secret diaries in which they reveal their wildest fantasies - Nino wants his far younger wife to become less inhibited and to this end he tries to engineer an affair between her and their daughter's fiancée, Laslo. 'Cheeky' sees Carla want to be faithful to her boyfriend. And yet, wherever she goes, she always ends up finding a new lover. Take the time she went looking for a flat in London: she embarks with nothing but the best intentions, but then, in almost no time at all, she's involved in a lesbian tryst with the estate agent! What's a girl to do? Whilst in 'All Ladies Do It' Diane (Claudia Koll) and Paul (Paolo Lanza) maintain a happy marriage thanks to the excitement generated by her extra-marital affairs. Out and about in the world, she can't help but indulge in a series of sexual adventures, and Paul just loves to hear about it all when she gets home. However, one day, when Diane returns home with bite marks on her person, it all gets to much for Paul and he explodes into a jealous rage.
