The US government is in need of horses for the war, and patriotic ranchers try to do their part. But their efforts are hampered by a group of outlaws (led by Richards) who want to rustle the ponies and get the cash for themselves. Leave it to Rogers and company to save the day. This
twist on the common B western cattle-rustling plot is fairly standard but a good entry in Rogers' popular series. In between the action, Rogers, along with the Sons of the Pioneers, manages to croon a few tunes, including "Sagebrush Symphony," "Blue Prairie," "Who Am I?" and "Curley Joe" (Tim
Spencer, Bob Nolan).
