Near Charleroi, Colin lives alone with his mother in a dilapidated house which caves in each day a little more. Facing misery, he writes with his buddies in his room, transformed into a kind of improvised "youth centre". Rap. As safety valve and as necessity. The only way they have found to speak of this poverty in the heart of Europe which is not even visible anymore. Even through our television sets. As long as the house stands, they won’t drift outdoors. As long as they write together, they won’t fall. "Before the Walls Fall" conjures up a youthful generation of the excluded, at the edge of a precipice.
