Charles Starrett once more dons the mask of mysterious do-gooder "The Durango Kid" in Columbia's Challenge of the Range. Wandering cowboy Steve Roper (Starrett) is hired by the Farmers Association to stem the activities of a group of gunmen who are driving ranchers off their land. The most likely suspect turns out to be innocent: the real culprits are within the Association itself. With the help of the chief suspect's son, Roper brings the crooks to justice.
