Northwest Mounted Policemen Fitzgerald and Herrick, who are later joined by Indian guide Uncas, have been detailed to track down a gang of whiskey-runners. They stop at a farm operated by "Big" Moore; and there Fitzgerald attracts Moore's daughter, "Honey," who has grown distrustful of her childhood sweetheart, Bob Thiele. The Mounties track the smugglers to their lair and rout them; but afterwards, Herrick is killed by a mysterious shot aimed at Fitzgerald. Uncas investigates and finds a clue pointing to Honey's brother Dave. Thiele, however, is revealed as the true murderer and the leader of the smugglers. Thiele defeats Fitzgerald in a fight and is about to shoot him when he is struck dead by lightning. Fitzgerald reports back to headquarters but returns to claim Honey as his bride.—AFI
