Cowboy Mark King (Tom Mix) comes to the aid of an old miner, Honeycutt (George Berrell) who, in gratitude, reveals the location of a secret gold mine. To get to the mine, however, King must fight an evil claim jumper, Gratton (Robert Cain), whose fiance, Gloria (Alice Calhoun), he once saved from falling off a cliff.
