Loner government agent Singin' Sandy Saunders (John Wayne) witnesses what seems to be a stagecoach robbery, committed by young Fay Denton (Cecelia Parker). But Fay is actually just trying to get her hands back on her own money in order to keep it from thieving stooges Bert (Al "Fuzzy" St. John) and Elmer (Heinie Conklin) and their boss, local land grabber James Kincaid (Forrest Taylor). Saunders then teams up with Kay to fight off the gang and derail the criminal plots of the greedy Kincaid.
