In the first of his 16 Westerns for Monogram, John Wayne plays Singin' Sandy Saunders, a drifter who witnesses what he at first believes to be a stage robbery. In reality, the "road agent" is a girl, Fay Denton (Cecilia Parker), and she is "stealing" her own money in order to prevent a phony stage holdup further down the road. As Fay's father, Charlie "Dad" Denton (George Hayes), explains, the culprit behind a rash of pretend stage holdups committed by two bumbling drivers (Al St. John and Heinie Conklin) is James Kincaid (Forrest Taylor), who is also forcing the local farmers off their lands by demanding an outrageous price for his water. When Sandy appears on the horizon, Kincaid engages a notorious gunman, Slip Morgan (Earl Dwire), but Sandy disarms the bandit for good by shooting him through both wrists. Much to Fay's disgust, Kincaid quickly hires the newcomer, now known as "the most notorious outlaw since Billy the Kid," and Saunders suggests that they dynamite Dad Denton's well, the only other available source of water in the area. It is all a ruse, of course, and Sandy soon reveals himself to be a government agent in disguise.
