 In this entry of the long-running Durango Kid series, renegade Henry Mandel (Bob Wilke) and his henchmen Paul Drake (Rory Mallison) and Carson (Zon Murray)have discovered gold on an Indian reservation and plan on getting rid of the Indians by, disguised as Indians, attacking wagon and supply trains and Army units and laying the blame on Chief Lone Tree (John War Eagle) and his foster son Swift Eagle (Jock Mahoney billed as Jack Mahoney.) Army Post Commander Major Markham (Fred Sears)and his aide, Lieutenant Robert Pierce (Marshall Reed), fall for the scheme, but Indian Agent Steve Holden (Charles Starrett), in his guise as the Durango Kid, uncovers the plot and, with the aid of Swift Eagle and Major Markham s soldiers, brings the renegades to justice.
