Shadows of the north (1923)

Ben Darby and Pancake, his father, are owners of a mining claim in Northwest Canada. Ben goes to war, leaving Pancake to run the mine. During Ben's absence three claim jumpers take possession of the mine: one of the men is the father of Beatrice, Ben's sweetheart; another, a rival suitor. Pancake is murdered when he and Ben plot to regain the claim. Ben kidnaps Beatrice, resolving to obtain revenge through her. Ben finds that she knew nothing of the stolen claim and that her father was innocent of Pancake's murder. Ben then resolves to find the culprit and bring them to justice.
