Texas Rangers Tex Wyatt (Dave O'Brien) and Jim Steele (James Newill) arrive in Thunder Gap as undercover Rangers to investigate the hijacking of supply wagons of food for the miners. They come to town as members of a medicine-wagon troupe headed by another Ranger, Panhandle Perkins (Guy Wilkerson). Tex discovers the offices of the Hard Rock Mining Company being robbed by Ed Ransom (Jack Ingram), owner of the local freight company. One of Ransom's gang slugs Tex and kills an official of the mining company. Ransom tells the townspeople he arrived at the scene too late to stop the robbery and the killing and blames Tex.—Les Adams <[email protected]>
