Charles Starrett makes his final appearance as The Durango Kid, this time as Steve Reynolds, a postal inspector who has gone underground to catch the bad guys. His longtime sidekick, Smiley Burnette appears as an itinerant optometrist who is hardly in the plot line of the film. Jock Mahoney plays Jack Mahoney, an eastern educated dude who has come back home. The Durango Kid teaches Jack how to draw and fire a six-gun, and the two ultimately work together to bring the outlaws to justice.
