During World War II, Roy (Roy Rogers), his sidekick, Frog (Smiley Burnette), and his loyal crew, The Sons of the Pioneers, are recruited by Texas governor Shuville (Russell Hicks) to investigate sabotage in the Lone Star State. They soon discover that Nazis and other axis sympathizers have been destroying warehouses containing supplies for the U.S. war effort. Roy saves the day by defusing a bomb meant to disrupt train service and brings the criminals to rout.
