Tony, Big Bill, and our protagonist, Squirt, are attacked by a gang and narrowly escape to lick their wounds. Their secret tree house is now exposed and ruined by the gang. They choose to up the ante, seeking revenge, thereby escalating the battle. However, there may be a slight hitch as the rival group is led by Fat Harold, Big Bill’s cousin. The trio decide to raid the rival gang’s hideout; stealing items and trashing the place. The war is on. Three against twelve are bad odds. Out-manned, out-sized, and outsmarted, they are shocked when Big Bill, their strongest and bravest, is captured and held for ransom.
All they need is an army--or a fantastic plan. Squirt and Tony must face their fears and rescue Big Bill from the clutches of the gang led by the formidable Fat Harold. Bill's very life and limb may be at stake. Or are they?
