Buck hires saddle tramp Orville Kilroy, who hides his criminal past and quickly becomes the most popular hand on the Cannon Ranch. Blue admires Kilroy's ability with a gun, the bunkhouse gang respects him as a top hand, and John Cannon is fascinated with his chess game. Telford Burris and his two sons trail Kilroy to Tucson and accuse him of running out with the money from a robbery. When the Burrises corner Kilroy, Buck must help the new hand to keep Blue's idol from crumbling, or turn the thieves over to the law.
