Dobbs is kidnapped by a gang headed by John Munro (Robert Filmer`), owner of the saloon where Dixie works. She writes Steve, and the Durango Kid and his sidekick Smiley (Smiley Burnette) ride out to help. Meanwhile,henchmen Rankin (George Chesebro) and Slade (Zon Murray) are vainly attempting to learn the location of the treasure from Dobbs.
