Raoul and his wife Solange are eating in a restaurant when Raoul expresses concern with Solange's apparent depression, as she eats little, suffers migraines and insomnia, and also sometimes faints. He finds another man in the room, Stéphane, to be her lover and hopefully enliven her again. Stéphane is puzzled by Raoul's plan, but gives in to his desperate appeals for help. The two men take turns sleeping with Solange, and both try to impregnate her without success, believing a lack of a child to be the source of her depression. Stéphane also shares his love for the music of Mozart and Pocket Books with the two and their neighbour grocer. The music inspires the men, but not Solange.
