The film is about the parallel desire of a widower and his three sons for their new housekeeper. The film challenged sexual taboos by presenting and mixing such themes as a teenage male sexually harassing an adult woman and her eventual rapacious response.
Following the death of his wife, a father of three sons (aged 18, 14 and 6) hires an attractive young housekeeper named Angela (Laura Antonelli), and soon becomes engaged to her. His sons are also infatuated with Angela, and each of them uses their particular way to approach and capture the apparently innocent and naive young woman, and to see more of her body. But only one of them succeeds in dominating and conquering her: the middle son, the teenager Nino. He blackmails her into eventually tolerating his increasingly aggressive physical sexual harassment.
