Roland Durand (Jean Yanne) and his wife Corinne (Mireille Darc) embark on a weekend getaway to the French countryside. Each is contemplating adultery as they head for the coast, but end up ensnared in a traffic jam along the way. Hilarity ensues in this absurdist romp as it devolves into all manners of human folly and destruction, and the fated couple encounters such colorful characters as the leader of the FLSO (Jean-Pierre Kalfon) and Saint-Just (Jean-Pierre Léaud).
