Brigitte Laurier (Brigitte Bardot), daughter of the President of France, is madly in love with Michel Legrand (Henri Vidal), the chief of staff of her father. He tries to evade her, but she follows him to the airport as he meets his mistress, Mrs. Wilson (Madeleine Lebeau), who intends to divorce her husband to marry Michel. He continues to shut down Brigitte's repeated sexual advances, but he finds that hard to do, as she has just appointed herself to an internship as Michel's secretary.
