A large and well-organized band of cattle thieves, headed by an educated "easterner," is rustling cattle from the X Bar X, 8 X 8, and other local ranches. The rustlers are so skillful that Mr. Manley realizes that only a concerted effort by the ranchers will put an end to their tyranny. He organizes a large force to track and locate the rustlers and put them out of business for good. The trail leads into the magnificent but little-traveled terrain of the labyrinthine Rustlers' Gap.
