The standard Roy Rogers musical western Bells of Rosarita is enlivened by a cute last-reel gimmick. Rogers is appropriately cast as a cowboy star who invariably rescues the heroine from the villain in his movie vehicles. But when Sue Farnum (Dale Evans) is cheated out of her inheritance by the duplicitous business partner (Grant Withers) of her deceased father, Roy finds out with startling suddeness that Real Life isn't like the movies. In order to rescue this genuine damsel in distress, Rogers enlists the aid of his fellow Republic sagebrush stars Wild Bill Elliot, Allan Lane, Don "Red" Barry, Robert Livingston, and Sunset Carson-each astride his own "celebrity" horse. So well-received was the climactic "hero rally" in Bells of Rosarita that the device was repeated again and again by Republic, most memorably in the 1950 Rogers starrer Trail of Robin Hood.
