Justine and Rémi Blanchet are preparing to marry their daughter Capucine to the mayor's son, Enguerrand Laville. This union will grant them access to the holy of holies, the very exclusive Club Ravel, of which the groom's parents are prestigious members. Their perfect plan, however, presents a problem, and not a minor one: Justine discovers during a surprise visit to her office that Rémi lost his job six months ago. When she learns that a wave of burglaries is sweeping the neighborhood, the mother has a crazy idea: fake a burglary, copy the modus operandi of real burglars, and file a claim with the insurance company. She ends up convincing Rémi, or rather forcing him, to follow her in this madness...

Although now full members of the Ravel Club, a rumor is circulating, claiming that Rémi is an imposter and that he is unemployed. More than ever, they must prove that they belong. At the New Year's party, Justine and Rémi dress up to dazzle their guests, but caught up in the excitement of the moment, Rémi bets his (fake) luxury watch in poker... and loses it. Justine then makes him realize, but too late, that when his poker partner discovers that the watch is fake, he will be unmasked as an imposter, once and for all! At the same time, Rémi is in deep trouble for his stupid shoplifting: Kathy, a police investigator and caring friend, asks him to go to the police station as soon as possible to help identify the suspect from a composite sketch... His own.
