Arthur and Gustav are total opposites. When their parents decide to move in together, the boys have to share a room with each other. They solve the problem by building a "wall" in the room. When the boys are unfairly accused of stealing apples, they decide to try to find the real thieves themselves. This adventure helps the boys understand that the best way to do it is to do it together.
