Hills of Oklahoma, a remake of Gene Autry's Call of the Canyon, stars singing cowboy Rex Allen, playing himself, as the newly appointed head of a cattlemen's association. In the film, Allen is tasked with leading his fellow cattlemen against a greedy meat-packer, Robert Emmet Keane (Charles Stevens) and his son Robert Karnes (Brock Stevens). They own the railroad lines giving them a great deal of power over the local ranchers who want to move their cattle. Instead of dealing fairly with the ranchers, they charge exorbitant fees leaving the ranchers no choice but to find an alternative. Allen leads his men to drive their cattle to a different rail station and a friendlier buyer, Kate Carney (Elisabeth Risdon). They are opposed by Keane and son at every turn and undermined by covert henchmen Hank Peters (Trevor Bardette). Hills of Oklahoma features the action and music that are the trademarks of the Rex Allen film series.
