Molsheim in Alsace: a local mission welcomes young people from across the region. It is the "big" town upstream of the working-class valley of La Bûche, an isolated area that is suffering the full brunt of unemployment and the depopulation of its villages. Dorian, Tiffany, Sandra, and the others are between 17 and 20 years old. Without jobs or training, these young people struggle every day to break out of their inertia. Yet some of them have not left their rooms for over a year when they arrive at the local mission. By joining the Youth Guarantee program, they hope to find a structured environment that will help them face a world of work that they find difficult to understand.
