Living in cramped quarters with Charley, an architecture student, four of his friends force him to dress up as a woman and play the role of his own godmother in order to rent Mr. de Saint-Sevran's mansion at low prices. The result is a series of misunderstandings and comical situations that only end when the real godmother arrives.

Cohabitant à l'étroit chez Charley, étudiant en architecture, quatre de ses amis le contraignent à s'habiller en femme et à jouer le rôle de sa propre marraine pour louer à bas prix l'hôtel particulier de Mr de Saint-Sevran.
