At their annual summer building club ‘Camp Scrap Wood’, best friends Ziggy (12) and Bas (12) find themselves on opposing sides for the first time in their lives. A different secondary school, their parents’ expectations and falling in love with a girl cause an almost forgotten argument to become an all-out battle between the two boys. As they work on their constructions, the boys begin to fight, each with the help of their own group of young builders. Initially, tougher Bas fights hard, but he soon has doubts about the argument. Meanwhile, the gentle Ziggy gradually toughens up and becomes determined to win.
