Gene Autry, star of a singing show with the Cass County Boys billed as "Gene Autry and his Texas Rangers," is mistaken for a real Ranger in the tough town of Mountain City. Gene soon swings into action to help Jen Larrabee, the owner of a toll road who is having trouble with the local eye doctor and a local gambler who want Jen to relinquish her property which contains valuable mica deposits. In an exciting showdown, Gene outsmarts and outfights the villains and then, with the help of his sidekick Smiley Burnette and the Cass County Boys, turns them over to the real Texas Rangers.
