The Durango Kid rides again in Lightning Guns. As ever, the masked Durango (alias Steve Brandon) is played by Charles Starrett, who this time around is on the trail of a gang of cold-blooded killers. Rancher Dan Saunders (Edgar Dearing) is held responsible for the killings because of his opposition to a politically expedient dam project. Durango believes that Saunders is innocent, and he intends to prove it.
