Norwegian winter, 1915. On the island Bastøy, outside Oslo, a group of young boys aged 11 to 18, are held in an institution for delinquent youth, notorious for its sadistic regime. One day a new boy, Erling, arrives, determined to escape from the island. After a tragic incident, he ends up leading the boys in a violent uprising. When the boys manage to take over the island, 150 soldiers are sent in to restore order.
Unfortunately the movie King of Devil's Island is not yet available on HBO Max.
