Border Vengeance.

After Wes Channing's partner, the feckless Buck Littleton, loses his half-interest in their ranch to gambler Flash Denby, Wes stands up against the sheriff's men when they try to seize the ranch-- land that has a gold mine on it. Denby tries to trick Mary Sims, granddaughter of Wes's neighbor Rufe Sims, into signing over the rights to the land. Denby's machinations are all set in order-- but Wes's right hook may prove to be a hell of a monkey wrench!
