Loner government agent Singin' Sandy Saunders witnesses what seems to be a stagecoach robbery, committed by young Fay Denton. But Fay is actually just trying to get her hands back on her own money in order to keep it from local land grabber James Kincaid. Kincaid is terrorizing the whole town by withholding the water supply from the ranchers and jeopardizing everyone. Saunders then teams up with Fay to fight off the gang, but will this duo be enough to derail the criminal plots of the greedy Kincaid? Filmed early in John Wayne's career, Riders of Destiny was his first film for Lone Star but the unmistakable swagger is already in place!
