Some teenagers sign up for the contest: "Describe your neighborhood", whose first prize is a trip to Milan. As the youngsters are football fans and fans of Milan AC, they decide to describe the neighbourhood with a rap song, and record a video. Archie Shepp, who also lives in the neighbourhood, watches them and decides to give them a hand.

In Belzunce, in the heart of Marseille's rap scene, the Guest Clique is preparing its next concert. But one of their members, K.Rhyme le Roi, harassed by a man in a BMW, disappears. Sista Vertu, DJ Rebel and Cash find him and accompany him on his run.
