Promoted to wrestling champion by chance, Tonin, known as le Bourreau de l'Ardèche, moves to Paris. He is quickly snapped up by Monsieur Bob, a self-styled manager who, in reality, hides his dealings under the cover of a nightclub, but who is also Tonin's regimental buddy. So Tonin acts as a front man, while Bob provides him with fake victories. The beautiful Wanda, the gangster's mistress, appeals to Tonin; she's charitable and sets him on the right path. He returns to the Ardèche and marries the daughter of the village mayor, after learning what a dangerous protector Bob is.
