In the Swiss canton of Vaud, any citizen can be named a legal guardian and is obliged to accept this responsibility. On occasion, the guardian can be named at random...
For everyone who knows him, JEAN-PIERRE, a university professor, is at the peak of his career. JEAN-PIERRE is a married, discreet and modest man with the highest moral standards. But the truth is that he has never been able to disclose his homosexuality to his entourage and that he's living happily with ARMANDO. To please his late mother, he even went through a paper marriage with ALICE. When JEAN-PIERRE learns that he has been named the legal guardian of ANTOINE, he runs to complain to the judge who, in reply, offers him the help of a social worker! Threatened with a surprise visit from this social worker, fearing that she will discover his double life, JEAN-PIERRE asks ALICE to help him out: he wants her to move in with him until things blow over! With a woman around the place (ALICE), a recently arrived teenager (ANTOINE), a furious, hidden lover (ARMANDO) and an increasingly annoyed JEAN-PIERRE... ANA, the faithful maid, has trouble dealing with things at the apartment. In this crazy situation, JEAN-PIERRE is finding things hard to deal with too.
