A closeted Swiss professor's closely guarded sexuality threatens to become front page news when he is appointed guardian to a recalcitrant teen in this light and lively comedy starring Jean-Calude Brialy and Sabine Haudepin. Swiss law states that any citizen can be appointed guardian to a child and must assume that responsibility if so named. When outwardly straight, happily married professor and author Jean-Pierre learns that he has been named guardian of an orphaned teenage boy, his attempts to discourage the judge from placing him in charge of the boy prompt the magistrate to launch an investigation into his suitability for the task. Realizing that his livelihood is on the line, Jean-Pierre attempts to repair his relationship with Alice, the woman and friend who once married him as a favor. As the teen he has been placed in charge of takes the initiative to move in with him, Jean-Pierre's secret threatens to become the talk of the town and his life begins to unravel at the seams.
