Two leather-jacketed motorcycle gang members ride into town and steer the Sugar Creek Gang into a dangerous adventure. Two mysterious boxes, one from Palm Tree Island and the other offering an anonymous reward, are at the heart of the mystery. Before it's solved, the Gang find themselves held hostage in Old Man Paddler's cabin. Join the Sugar Creek Gang as they see the love of a father in action, the kind that will track down a son who has gone astray.
