The Flower of No Man's Land.

Echo, the orphaned "flower of no man's land," has been raised by an Indian foster father, Kahoma. Then, when opera singer Roy Talbot goes West to recover his health, Echo falls instantly in love and forgets all about Big Bill, her cowboy sweetheart. Roy marries Echo and takes her back East, but soon after returning to his adoring public, he loses all interest in her. Finally, Echo leaves Roy and goes back to the wilderness, where she discovers that Roy had already been married when they met and had deserted his wife years before. For so deceiving his adopted daughter, Kahoma tracks Roy down and kills him, while Echo forgets about her big-city unhappiness and returns to Big Bill, with whom she makes plans to marry.
