The hardships and perils of a winter on the Yukon cannot kill the love of home and family firmly implanted in the hearts of the two brothers who have suffered all the dangers of that Arctic climate to win the fortune that, by lucky chance, comes within their grasp as the long winter breaks, and they prepare to start, by dog sledge, back to the States by way of Dawson City. In Dawson they wander into a dance hall, and the proprietor, noting their well filled bag of gold dust, induces his daughter, Lou, to try to steal it, but for the first time in her life her heart is touched with tenderness by the avowal of love at first sight by Walter Weir, one of the brothers, and she agrees to accompany the boys back to their mother in Vermont. She sets a signal in the window of her cabin, but her father overhears the plan and spoils it. The boys prepare to leave Dawson City, and after they have successfully negotiated one of the greatest dangers of the Chilkoot Pass, that of dropping down an almost perpendicular hundred-foot cliff, dog team and all, they are waylaid by the vengeful gambler, lassoed and left to perish in the biting Arctic cold. Lou rescues them in the nick of time, and with the aid of the Yukon Police Patrol the boys start a hundred-mile pursuit to regain their stolen fortune. The Yukon police, after a standup battle with the cornered murderers, succeed in killing one of them by a lucky shot, and the other is left to the same cruel fate that he had so nearly accomplished upon the brothers, while Lou and the brothers start on their journey back to civilization.
