1983, Paris region. While Daniel, a young DJ passionate about funk, returns from San Francisco, where he discovered hip-hop culture, two teenagers spend more or less quiet days in a city of Saint-Denis: the discreet Bruno, with a football talent, and the gambler Didier, raised by a violent father. Fascinated by an American dance show on the forecourt of the Trocadéro, Bruno and Didier get closer. Daniel, on the other hand, makes his debut as a DJ in a pirate radio station, determined to introduce the French public to the music of tomorrow...
While waiting to find her father, who has abandoned them, she tags the walls of the Olympiads with her friend Dora. She will invent a name for herself: Lady V. Daniel has settled down with Béatrice, who works as a dancer in a hostess bar. He embarked on the recording of his first disc with the means at hand... In Saint-Denis, Bruno and Didier trained in breakdance. Their objective: to enter the Grange-aux-Belles district to challenge the best, such as the arrogant Solo and his crew the Paname City Breakers.
Daniel has made a name for himself: DJ Dee Nasty. He organizes block parties on the vacant lot of La Chapelle, in Paris. Bruno goes there with his band of graffiti artists. Didier, fleeing his father, joined a troupe of dancers abroad. He returns with the firm intention of conquering the capital, but Bruno reproaches him for his inconstancy. The latter keeps thinking of Lady V, a fly girl with a strong character that he spotted in a report at Bando, an outstanding graffiti artist who comes from the upscale neighborhoods. To get out of the financial mess, Béatrice and Daniel plan to shoot in a porn film...
