In Saint-Denis, at the Stade de France district leisure center, the time for the fair comes with summer. The day before D-Day, at the Koné's, Oumou and Bakary bicker as usual while their father learns of an important letter from the Prefecture. On the morning of the party, on the other side of the ring road, host Benjamin is very late to help with the preparations and hides his lack of enthusiasm under his hangover. Around the stadium, the security system is set up for the evening concert.
