Shopkeeper Victor Garnier has naively invested his family's life savings in an African mine, on his banker's recommendation. When the mine is nationalized, rendering the stock worthless, he considers himself shamelessly robbed by the bank; it seems only fair to him to return the 'favor' and rob the bank, teaming up with the whole family as they were all duped. Even for professionals such an enterprise -he decides to dig a tunnel- is quite demanding, but for simple commoners it's daunting, as they also have their personal downsides; thus Victor's wife has a most unwelcome tendency to blurt out the truth, even to the grumpy local copper: a crazy risk when you need to keep a criminal plan secret.

Maroîs, the fairground bon vivant, spends most of his time around a bottle of wine, in the company of his friend Michaux, with whom he was once a sailor. He neglects his wife Monique, a pretty girl much younger than himself. Suffering from this indifference, she seeks imperfect and fleeting consolation, first from Michel, their friend's son, then from Jean-Louis, a young mechanic who has helped out with Maroîs' truck and won his trusting friendship. Michel, jealous, tells the showman of his misfortune. He leaves to kill his wife's lover. The latter, wishing to separate the antagonists, seriously burns herself by knocking over an autogenous welding block, which explodes. Taken to hospital, she asks for and receives her husband's forgiveness.
