The film tells the story of a ménage à trois in which two men share a woman, Solange, to cure her of an unexplained depression, with many symptoms. Everyone, including their neighbor, a vegetable vendor, agrees that she needs a child, yet she fails to get pregnant by either lover. The three take a job running a kids’ summer camp where they meet Christian, the precocious 13-year-old son of the local factory manager. It is Christian who restores Solange to laughter.
