 Unknown to Joan Manning (Polly Ann Young), her trading post partner Weathers (William Royle) is operating a counterfeiting ring. When miner Jim Smithers (Budd Buster) brings his gold dust in, Weathers pays him off in counterfeit money. Jim s drunken brother, Bill (Al St. John), comes to the post and Weathers hears him say that Jim is leaving the area for good. Weathers sends Hawks (Karl Hackett) to kill Jim and retrieve the bogus money. RCMP Sergeant Renfrew (James Newill) and Constable Kelly (Dave O Brien) find Jim s body, and Renfrew hurries for Jim s cabin to search it. He is attacked by Weathers  men who have found the money. Renfrew is suspicious when Bill Smithers body is found, supposedly a suicide, with a note he had burned the money. This leads the Mounties to suspect counterfeiting. Kelly follows Manti (Chief Thunder Cloud as Chief "Geronimo" Thundercloud), an Indian who works for Weathers, to the gang s hideout and is captured. But Renfrew is trailing Kelly.
