Dark Cloud, an Indian trapper, is unjustly accused of robbing the trader's store. Winston King forces him to leave the country and warns him never to return. Arnold and Dorothy, the children of King, while canoeing, lose their paddle and drift toward the falls. Dark Cloud hears their cries for help. Leaping upon a log, he follows them. The Indian is just in time to save the children from the rapids. He brings them ashore. While Arnold and Dorothy are pleading with their rescuer to go home with them, a shot is heard. The children and Dark Cloud discover Petro, a half-breed, who has been shot by his Indian partner. Dying, Petro confesses that they had been quarreling about the division of the money they recently stole from the trader's store. The half-breed points out the direction his partner has taken, confiding to Dark Cloud that the Indian has the money. Dark Cloud hunts down Hawkeye, the thief, captures him and brings him back to where Arnold and Dorothy are waiting with the wounded Petro. By this time King, who has been warned of his children's danger, has reached the place. Dark cloud takes the stolen money from Hawkeye's belt and hands it to the trader. Refusing to accept any reward, the Indian walks proudly away.
