At seventeen, Mimi lives in Paris, far from her parents. And since valor does not depend upon age, she is already a kept woman. The trouble is that Daddy does not know the truth and when he comes to Paris to bring her back home (an inn where she is supposed to work as waitress for the summer season), she is a bit embarrassed. She and her rich lover think they have found a way out: Mimi's lover will pose as her employer. But things do not go according to plan...
