In cell 21 of a modern privatized penitentiary, three men are forced to share their lives. Francky got ten years for armed robbery. His wife has left him for his former partner and this is eating at him. Francky has nothing to return to and lives life within the walls out of his inner anger. Grandjean is an innocent college student, tricked by a wisecracking drug runner. He has entered a world of which he did not suspect the existence and does not want to recognize, even though he is in the middle of it. Kader, an immigrant from a suburb of Paris, is routinely serving his sentence. He has been here before and will definitely return. The origin of the dance has become second nature to him. Kader is a friend until you run out of cigarettes.
