Jules Vachon, a pharmacist, has two sons, Gabriel, a steady-minded young man dedicated to his job in the pharmacy, and Gaston, a good for nothing whose only talent is to seduce rich women and take money from their pockets. But it is Gaston who is hailed as a great man when he returns to his native village thanks to his deep pockets.
Baronski has had enough of being a small-time merchant and decides, aided by his daughter Esther, to try his hand at big business. Why not be a film producer for instance? But it is easier said than done and he is soon relieved of 100,000 francs by a crook. Undaunted, he produces a film written by a young scriptwriter, Maurice Rogier, discovered by his daughter but does not believe it could become a success. Esther, for her part, decides to have "L'ange que j'ai vendu" shown in a local movie theater and the film immediately proves a hit. All is well that ends well, Esther marrying Maurice into the bargain.
