The Man From Oklahoma is set during a 20th century renactment of the 19th century Oklahoma land rush, but if patrons wanted to assume that the film had something to do with the Broadway musical hit Oklahoma!, that was certainly their privilege. Roy Rogers is on hand to help Peggy Lane (Dale Evans) stake her rightful land claim, despite the machinations of the villains. This time, Roy's comical sidekick Gabby Whittaker (Gabby Hayes) gets to have a romantic entanglement of his own, in the ample form of Peggy's self-style duenna Grandma Lane (Maude Eburne). The musical portion of the program includes several juke-box hits along with the usual quota of cowboy ballads and hillbilly novelty songs. As was customary in the Roy Rogers vehicles of the era, action takes a back seat to music in Man From Oklahoma.
