Lydia, a model, and Helga, a flight attendant, live together and share the rent. Lydia gets a job in a cabaret, but the owner soon asks her to become a trainer, which she refuses. To punish her, he locks her up in his house. Thanks to her friend Helga, the police take a closer look at the manager's reprehensible actions.

Thanks to the complicity of his friend Laura, Jo, sentenced to 20 years in prison, escapes from the central prison. Hiding in an old disused mill, Jo sends his young friend to a certain Freddy, gangster and nightclub owner in Pigalle, who owes his freedom to Jo's silence. But Freddy sends two of his henchmen to the mill where Jo is hiding, to kill her.
