Mauro is a priest with strong religious convictions. He goes to his cousin Dora’s country house, for a retreat. But she has other plans and invites all her friends for a birthday party, which soon turns into an orgy. For the priest, this is unexpected and unwelcome. Among Dora’s friends, there’s a girl, Ana, who despite her own problems (she had just quarreled with her husband, Dino), tries to comfort the priest, which upsets Dora, since the latter had always had a crush for his cousin. Will Mauro be able to resist the temptation he sees all around him?
