27-year-old Georges Rollin get called back from Paris by his father to their farm/inn, none of which he has seen for 25 years. He doesn't know why, but it turns out his father wants to consolidate the fortune of both branches of the family by marrying him to his cousin Blanchette Brunoy, despite the fact she and another cousin, Robert Vignon. On arrival, he's scared out of his wits by an uncle, discovers his great-grandfather's corpse, is accused of murdering an aunt and stealing the mysterious family fortune.
A typical French country family, you'd say, particularly if you're fond of TOBACCO ROAD. Every one of them has a nickname that everyone in the town knows about to exclusion of actually knowing their real names: Goupi Monsieur or Goupi Le Loi or Goupi Mains Gauches and they don't get along particularly well, but unite against outsiders. As the movie went along, it got darker and darker, and I thought director Jacques Becker had made a Clouzot-style picture. Was he trying to get himself banned, too?
Well, you'll have to see how it turns out. It's certainly entertaining, and familiar enough if you come from a large family.
