An art dealer in dire straits, after being ripped off by two crooks, one of whom owns a genuine painting by Gauguin while the other is an expert copyist, finds them again and, instead of killing them as he originally intended, joins in their game – with ultimately disastrous results.

Aimé Morin, a good-natured bookseller, is also one of the candidates in the local elections of his small town. He is well-liked by most but he also has political enemies. Among them is Lagarde, a journalist close to the latter. Lagarde takes advantage of Morin being on holiday in Paris to try and tarnish his reputation. His machination unfortunately works and poor Aimé finds himself mistaken for a sex maniac.

He was nicknamed Gueule d'ange (Angel's Face) because of his good looks, which enabled him to make a certain amount of money from wealthy ladies. Having given up on touching little Marie, he fell into the clutches of fashionable decorator Loina. Both love money, both go for it. Their characters bind them together. So much so that when Loina falls on hard times, Gueule d'ange would fly to help her. A loyal friend stops him. Loina leaves. Distraught, the handsome boy looks inward. It's time for him to settle down.
