Rod Drew, who is traveling to French Canada to track down the niece of his father's best friend, runs into a half-breed college chum, Wabi, on the train. After Wabi is framed in an on-board poker game, Rod helps him to escape from the ensuing shooting brawl. Rod and Wabi jump the train and are chased by authorities to an abandoned cabin, where they find a map to a gold mine and two skeletons, one, that of John Ball, the father of the girl he must find. Seeking refuge at Wabinosh House, a general store run by the unsuspecting Felice Newsome and her father, Rod and Wabi request that the map be stored in Newsome's safe. The map is seen by Benoit, a henchman of renegade trapper Jules LaRoque, who then plots to rob the safe but ends up kidnapping Felice instead. Through a decoy, Rod and Wabi rescue Felice, but a determined LaRoque sends gang member Marie La Fleur to Wabinosh House to pose as a bookkeeper and steal the map. Before she can break into the safe, Rod and Wabi, who secretly loves Felice, canoe their way to the map's location and discover not only the gold, but papers identifying Felice as John Ball's daughter as well. Caught by one of LaRoque's men posing as a Royal Canadian Mountie, Rod and Wabi are tied up with the real Mountie in LaRoque's hideout. Rod breaks free, and after several canoe and horse chases with the Mounties, the gang is apprehended and LaRoque is shot and killed. Pardoned by the Mounties, Rod and Felice say goodbye to a heartbroken Wabi and return together to Ball's ranch.
