Valentina (Edwige Fenech) and Giovannino (Ray Lovelock (actor)) are a wealthy young couple who return to their home in Iseo, Lombardy after honeymoon and it is revealed that Valentina is still a virgin due to her husband's erectile dysfunction. The news rapidly travels and soon there are many men who volunteer to deflower Valentina, including Giovannino's amorous uncle Federico (Renzo Montagnani) and their lawyer Caldura (Antonio Guidi) but Valentina is keen to resist their advances. On the other hand, Giovannino is getting increasingly bored with their sexless marriage made even more difficult by the sexual escapades involving his brother Gianfranco (Michele Gammino) and his insatiable German wife Brigitte (Florence Barnes).
