Range Law stars Johnny Mack Brown as "Nevada" and Raymond Hatton as "Sandy", the same characters they played in most of their mid-1940s Monogram westerns. This time, Nevada and Sandy, US marshals both, set out to collar some renegades who've been driving out the local ranchers. It's just possible that one of said ranchers is behind this land-grabbing scheme.
