Wade Beaumont (Dick Curtis), R. A. Kirby (Kenneth MacDonald) and Burke (Edmund Cobb), of the Caribou Trading Company, have reduced the miners and trappers almost to the point of slavery by charging them exorbitant prices for provisions. Beaumont threatens to quit and the other two are thrown in a panic, but a fistfight between Beaumont and Larry Daniels (Stanley Brown) gives Burke an idea. He stabs Beaumont with Larry's knife and RCMP Sergeant Neal Crawford (Charles Starrett) arrests Larry for murder. Neal's romantic interest in Larry's sister, Norma (Iris Meredith), makes this task difficult. Not happy at the evidence brought out in the trial, Neal takes a leave of absence and begins his own investigation. He ties up the gold at the trading company until a successor to Beaumont is appointed, and thus keeps Burke and Kirby from absconding with the gold. Norma and Neal see the crooks burn the evidence that will free Larry. Burke, Kirby and Jacques LaRue (Alberto Morin) clean out the vault and ride away, but are pursued by Neal and the Mounties.
