During a stopover, Morel, an airline pilot and Colette spin the perfect love. She hides from him that she is compromised in the actions of a band of criminals. She manages to escape her dangerous friends while a shootout wipes them all out.

This murder mystery is set in a Parisian cafe and examines the mysterious murder of a famed journalist and extortionist who is killed at his table in the cafe. Though the prime suspects are gathered together( including his wife and her lover, the gun-runner, the creditor, and a playboy) and all of them have motives, none of them did it. So whodunit?

In the elevator of two large Parisian buildings, a telegraph operator discovers the body of an elderly woman, Madame Mathieu, the owner of both buildings. Boucheron (Lucien Baroux), the local superintendent, is dispatched to investigate, along with his rival, Inspector Lambert of the "Sûreté" (Jacques Baumer). To solve the enigma, they scour staircases and corridors, visiting every floor of both buildings, courtyard and facade. Their gruff rivalry allows them to complement each other in discovering who committed the crime among a gallery of characters, humble or rich, who all have something to be ashamed of... A rare, fast-paced, picturesque comedy set against the backdrop of a police mystery.
