In Oklahoma, kindhearted outlaw Brick Willock rescues little Lahoma Gledware and her father Henry from certain death at the hands of his outlaw band. In the course of the rescue, he kills Kansas Kimball, the brother of the outlaws' leader Red Kimball, who vows vengeance against Brick. Brick renounces his life of crime, and after Gledware relinquishes custody of his daughter to marry an Indian princess, the old cowboy gives refuge to the little girl, raising her with the help of neighbor Bill Atkins. Years later Easterner Will Compton comes to Oklahoma to homestead, meets Lahoma and falls in love with her, but is forced to leave by Brick. While visiting Kansas City, Lahoma overhears Kimball plotting to kill Brick by swearing out a phony warrant for his arrest, but she foils his plan. Outwitted, Kimball takes revenge into his own hands and shoots Brick, only to fall in his tracks from Brick's own gun as the old outlaw breathes his last breath. Will returns to console Lahoma and the couple are married.
