The Story of a Despicable Sick Man
In the countryside of France, the housewife Esther (Danièle Gégauff) and Philippe (Paul Gégauff) have been living together for more than eight years with a daughter, Elise (Clémence Gégauff). 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 (Giancarlo Sisti) 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 (Paula Moore), who is a wealthy and independent woman. But soon he misses her dependence on him and their story ends in a tragedy.
"Une partie de plaisir", a.k.a. "Pleasure Party" (1975), is an unpleasant film by Claude Chabrol with the story of a despicable sick man. The humiliations of Esther are heartbreaking since she has a daughter and financially depends on Phillippe. The guy is one of the most obnoxious characters of serious films and what he does to Esther in the end of the story is repugnant. My vote is seven.
