John Wayne sings! Well, not really. His voice was dubbed here, but as Singin' Sandy Saunders he's still able to write the code of justice with a blazing six-gun! He's a government agent out to help a group of ranchers in their battle with a villain who is tying up local water rights. Also starring Gabby Hayes, Al St. John, Yakima Canutt, and Cecilia Parker, Riders of Destiny was filmed early in Wayne's career - it was his first for Lone Star - but the unmistakable swagger is already in place!
