When Raoul's wife, Solange, falls into a state of perpetual despondency, he tries anything to cure her -- including asking a total stranger to make love to her. But even with a new lover, her sadness remains. The two men are utterly baffled, until a neighbor offers an invaluable insight: might Solange want a baby' It turns out that she does, but after numerous attempts, neither husband nor lover succeeds in impregnating her. Then, one afternoon, the three head off on a field trip and Solange meets Christian, a precocious 13-year-old whiz kid who manages to get her into bed. Finally, with this boy, Solange finds contentment. But Christian's horrified parents immediately attempt to ship him off to boarding school. Solange, however, has no intention of losing her new-found happiness -- even if she has to resort to kidnapping to keep it.
