Married against her will to the Comte de Trivelin, Paulette Dupont shares her anxieties with her childhood friend Labaule. Warned too late to prevent the ceremony from taking place, Labaule follows the couple on their honeymoon and prevents the consummation of the marriage by repeatedly intruding on the couple's privacy. Put on notice by Paulette's parents to consummate the marriage, Trivelin - who believes himself to be at fault - consults a psychiatrist. The latter advises him to visit a lady of lesser virtue: Gloria. But Gloria's clientele includes Dupont himself - Paulette's father - and Labaule!
