Juliette Hardy is sexual dynamite, and has the men of a French coastal town panting. But Antoine, the only man who affects her likewise, wouldn't dream of settling down with a woman his friends consider the town tramp.

Around 1900, Zaza was the undisputed star of the "Variétés parisiennes". Bonded with pianist Cascard, she indulges in adventures and falls in love with handsome Bernard Dufresne. A short affair. Surprised by her friend's behavior, she believes he has a mistress in the provinces. In reality, he is married and Zaza, faced with her daughter, prefers to step aside. From now on, she'll live for her art, and will always refuse to renew her acquaintance with the man who made her suffer.

Although suspected and hunted down by policeman Sherlock Coco and inspector Hector, the Pieds Nickelés (Croquignol, Filochard and Ribouldingue) manage to save the legacy of Monsieur Miradoux, who will be very grateful to them.
