In 1875, wild horse wrangler Jud Holman returns to his isolated hometown of Tubac, Arizona, and faces the schemers who threw his father out as registrar of the Santa Cruz Land Office. Surviving a canyon ambush through nerve and luck, he dodges the combined forces of the Circle T and Bar J ranches. He is forced to pose as a U.S. Marshal, and risks exposure at the Circle T headquarters, owned by Jacob Tullar, the big man in the valley. Holman's chances take a stunning blow when he falls for Tullar's daughter. Where will his luck take him now? To bullets, blood and maybe death in a double showdown with Tullar and his lightning-fast gunfighter.
