They are three fishermen from the Old Port: Toinet, Pénible and Girelle. Two of them are in love with two pretty merchants. Not confident in their natural seduction, they decide to use drastic measures to be sure to attract and sustain the attention of these young ladies. This is how they approach them by posing as wealthy industrialists. But now the young girls, not to be outdone, present themselves as film actresses.

Bienaimé, a modest postman, in love with Janine, the village postmistress, does not know that he is the illegitimate son of the old Baron de Mondésir. The Baron dies and in happy amazement, Bienaimé finds he is the sole heir to the deceased's estate. But he should be careful, for two crooks, Waldemar and Erika, are after his newly-acquired wealth.

Outwardly, Monsieur Victor would appear to be the model citizen. A respectable Toulon shopkeeper, he has a devoted wife and is courteous and considerate to all who know him. However, beneath this veneer of respectability hides a notorious receiver of stolen goods, who trades with hardened criminals. Victor manages to keep up his double life without any difficulty until the fateful day when one of his partners in crime threatens to expose him. Fearing a scandal, Victor kills the crook in a moment of panic, using a shoemaker's tool. Naturally, the murder is blamed on a local shoemaker, who is sentenced to ten years' hard labour. Seven years later, the former shoemaker reappears in Toulon, having escaped from prison. The first person to recognise him is Monsieur Victor...

Sentimental and emotional problems for a certain Jean Mariole who can hardly really position himself between two mistresses.
