In the Canadian Northwest, Jen Galbraith lives in a tavern with her brother Val and her father Peter, a bootlegger who sells whiskey to the Indians. Val's friend Pierre resolves to win Jen, even though she is in love with Sergeant Tom Gellatly of the Mounted Police. When Val tries to retrieve some liquor sold illegally by the elder Galbraith to an Indian named Grey Cloud, the Indian insults Jen and Val shoots him. Tom is assigned to track down the murderer, but after he arrives at the tavern, Galbraith and Pierre drug him. Jen delivers the papers he is carrying to police headquarters, but when she discovers that they contain orders to arrest her brother, she shoots Tom to prevent him from going after Val.
