1983 film by Laurent Heynemann

François Maurey, the head of a computer company, has developed a product that's sought after by the Americans, but he refuses to sell it to them. While his wife Caroline is preparing to leave him after 25 years of marriage, François has to face various people in his life, including new arrival, Florence, a troubled and mysterious young woman who enters François's life and causes havoc.

Muriel, a writer nearing 50 whose older lover won't live with her in Paris, meets a man on a train - Samuel, an Arab. He's attracted to her and pursues her, dropping in, asserting himself. She's willing to connect. He's passionate, then boorish, then jealous and possessive. He seems fixed on "Who's the strongest?," while she wants respect and trust. She's self-possessed as well as sexually charged, willing to laugh, and alternately firm and forgiving. He has little money, no immigration papers, few prospects, and a gambling jag. What does each want, and why does she stick with it? Is this colonial strife, war between the sexes, or a love story?

When Batignole finds him, he feels sorry for the boy and lodges him, hiding Simon from Pierre-Jean and also from his wife. Later, two cousins of Simon meet him in the cellar of the grocery. When Pierre-Jean finds the children, Batignole decides to travel with the children to Switzerland.
