In the Paris suburbs, the ashes of the night's riots fall on the lives of young people. Games, rap, intimacy, boredom and tension resonate in the concrete.

Meanwhile, in the 6th arrondissement, the students of Fenelon high school meet between classes, kiss each other, share their fears and imagine their future. Sociologist Alain Touraine, who is old enough to be their grandfather, tries to make sense of a fractured society. He was welcomed with open arms in Latin America where his ideas still found an audience. Chronicle of a year in Paris.
