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.
