The railroad is coming, and three different factions - landowner Karl Ulrich/The Baron and his gang, led by Campo; railroad construction boss Homer Lathrop and his motley crew led by Scully and Irv; and a tribe of Indians led by White Eagle - have vested interests and reasons to stop the line's construction under the supervision of Tom Lane and his sister Carol. Undercover marshal Jim Grant (Jock Mahoney) and prospector Rocky are there to upset and hinder the raids by which ever band of malcontents is next in line.
Stunt man turned star Mahoney doubled himself in most scenes, and his footwear throughout the serial was a pair of Indian moccasins rather than the usual high-heeled boots. That wasn't done to be unique as much as it was done to save time when too came to such stunts as jumping from and running on slanted roofs. Stunt men did not, as a rule, care much for doing roof-top stunts in high-heeled boots, or even transfers where a boot heel could get hung up. In some of the Durango Kid films, where Mahoney doubled Charles Starrett, the footwear on Durango sometimes magically changed in mid-air.
