A philandering husband convinces his wife to have affairs, believing she can't find a lover as interesting as he.

Phillipe and Esther live an apparently idyllic life with their daughter, Elise. In an attempt to preserve this bliss, Phillipe decides that he and Esther should each have affairs, being sure to tell each other openly about them. The plan backfires with tragic results as Phillipe becomes engulfed in jealously.—Jim Wade

In the countryside of France, the housewife Esther and Philippe have been living together for more than eight years with a daughter, Elise. Philippe is an egocentric and self-righteous man and tells his wife that he has cheated her six times. She admits that she has never had a love affair, and he asks her to have sex with one of his friends. Esther meets the intelligent Habib during a dinner party at home and they have an affair. Philippe continues to sleep with Esther's friends, but soon he becomes jealous of the successive encounters of Esther with Habib. He humiliates her harder than usual, saying that she is stupid and belongs to a lower class. They move to Paris, and Esther changes her submissive behavior, working for Habib. She splits from Philippe, and he marries their friend Sylvia, who is a wealthy and independent woman. But soon he misses her dependence on him and their story ends in a tragedy.—Claudio Carvalho, Rio de Janeiro, Brazil
