The dentist Luciano has sex after hours with Sonia on the dental chair. Out of the blue, his old friend Marcelo appears in his office with a problem in one tooth, and Luciano invites him to have sex with Sonia, who is actually a call-girl. Marcelo and Luciano have not seen each other for many years, and Luciano tells that he is still married with Anita and he loves her. Marcelo tells that he is married with Ana and he is bored with his second wife. In retribution, the wealthy Marcelo invites Luciano to come to his apartment to have sex with women on the next afternoon. Luciano lies to Anita and tells that he needs to go to the doctor. On the next day, Marcelo receives the visit of his daughter while working with his secretaries Laura and Ms. Harriet. The girl asks his father to give a job to her friend Gina, who needs to work, and Marcelo hires her for translations. Then he meets Luciano and brings first the whore Mariana for his friend and then two other call-girls for them. Luciano arrives late at home and Anita finds his behavior strange. On the next morning, the servant Dora tells Luciano that Anita has traveled to visit her mother. Luciano schedules another encounter with Marcelo that brings Harriet, Laura and Gina to have sex with them. However, Anita and her friend follow Luciano and his wife finds the truth about Marcelo’s apartment and plots a revenge against her unfaithful husband.
