John Wayne is back in another of his "Lone Star" western series. Once again, Wayne plays a wandering cavalier who reveals himself to be a federal marshal in the final footage. This time, he comes to the rescue of orphaned Indian girl Nina (played by former "Our Gang" member Shirley Jean Rickert), the heir to an oil fortune. To thwart the bad guys, he disguises himself as an outlaw, briefly earning the disdain of heroine Clara Moore (Sheila Terry). The usual "Lone Star" supporting players George Hayes and Yakima Canutt are here joined by Jay Wilsey, who enjoyed brief fame in the late-silent era as cowboy hero Buffalo Bill Jr.
