Synopsis: The age-old enmity between cattle ranchers and settlers once again takes center stage in this slightly above-average Western filmed in Republic Pictures' Trucolor system. Walter Brennan plays Pop "Brimstone" Courteen, an ornery rancher who avenges the loss of the free range by robbing stagecoaches and banks. The Courteen gang, which also includes Pop's three sons, Nick (Jim Davis), Luke (Jack Lambert), and the reluctant Bud (James Brown), gets a bit of competition from The Ghost, a mystery outlaw who really is Marshal Johnny Tremaine (Rod Cameron). Tremaine's undercover investigation leads to McIntyre (Forrest Tucker), the sheriff of Gunsight, who is in the employ of the Courteens. In love with Molly Bannister (Adrian Booth), a settler, Bud turns against his ruthless family, but will Tremaine be able to save the boy from his father's wrath?
