Original title: L'entraîneuse

The young Suzy is a nightclub hostess in a cabaret in which Frehel is the star. Because one night she gets propositions from a rich widower who would like to have her as his girlfriend, Suzy wishes to leave this place, where she has no future, for a better one. Abandoned by her protector, a young hoodlum named Robert, she gets the occasion to get away from it. She decides to go on vacation on the Riviera and stay at the Chateau des Cedres, the former residence of a noble family that has been transformed into a bourgeois guest house by the baroness Saint-Leu. Shy and elegant, in her modest suit, Suzy stays there under the name of Suzanne Michelet and soon makes new friends among the young people of very wealthy families.
