17-year-old Prudence lives alone in Paris. After unsuccessfully shoplifting, she meets Marilyne at the police station, who introduces her to the motorcycle scene.
After the arrest, the policewoman is irritated because Prudence cannot give a contact person: Her father is in Canada because of an inheritance issue and her mother died two weeks ago. The two delinquents (Prudence and Maryline) quickly become friends. But Prudence’s newfound lease of freedom becomes complicated when she falls for a boy Franck who wastes no time in taking advantage of her naivety.
