In a quiet wood, a gray squirrel declares war on the machines that invade his wood, threatening his nest and tree. Taught words and how to use simple machines like the wheel by a young boy who names him Jack, the squirrel shares what he's learned with the other animals. Hoping to convince the woodland animals to fight with him, Jack has a new problem; the humans are now very interested in him. Even if Jack wins the battle, will he lose the war?
