Based on his personal memories, director Christophe Bohn narrates a little known chapter from the history of the German community in Belgium. As a child he discovered that his father had Nazi-German sympathies when he was only 12 years old. He never found the courage to confront his father. Only after his death could Bohn explore this dark piece of family history. The Boy is Gone is a fascinating journey into the past using archives, animation and moving testimonies.
