 Marshal Clark (John Merton) sends Lash La Rue (Lash La Rue) and Fuzzy Q. Jones (Al St. John) to break up a gang of counterfeiters, led by Jim McCord (Dan White), operating in a deserted village across the border. On the way, they chase off three outlaws in pursuit of a wagon carrying Frank Evans (Ted Adams) and his daughter Jane (Nancy Saunders), who are trying to escape from the outlaw s hideout. Lash leaves Fuzzy to guard the buckboard while he escorts the Evans  to a friend s cabin, and returns to find Fuzzy missing and a note, signed by the Frontier Phantom, advising him to get out of the country. He returns to the cabin and also finds Evans and his daughter gone, but runs into the Frontier Phantom, who is his exact double and his long-lost twin brother. They fight, Lash wins and takes the Phantom s clothes and heads for the outlaw stronghold. There he finds Fuzzy has been made chief cook-and-bottle washer and janitor. McCord thinks there is something different about the Phantom and sends henchmen Turk (Steve Dunhill)and Buck (Lee Roberts) to trail him. Lash gets rid of Buck, but Turk returns to McCord s with the news of his real identity. Lash returns and is soon involved in a one-sided gun battle. Fuzzy goes for help and encounters the real Frontier Phantom who rides to the gun fight to join his brother.
