A gunfighter attempts to goad Blue into a shootout. Participating in his first trails-end celebration that traditionally follows a grueling cattle drive, Blue joins his father John Cannon, Uncle Buck and Manolito and the town's other weary but happy cowhands in observing the occasion. A barroom argument develops between Blue and short-tempered Johnny Keough, who invites young Blue outside to settle the matter with their guns. Well aware of the obvious advantage the well-known gunman Keough has over him but also concerned about his own pride as a result of being publicly challenged, Blue finds himself facing one of the most important decisions of his life.
