The Ranger Busters -- a trio of law-enforcing cowboys consisting of Crash (Ray Corrigan), Dusty (John King) and Alibi (Max Terhune) -- encounter a man who has been ambushed and left for dead while traveling to a ranch he has inherited. While the injured heir recuperates, the Ranger Busters ride over to the ranch to investigate. They uncover a plot concocted by Roger Denby (Glen Strange), a lawyer who wants to get his greedy hands on the oil the ranch is sitting on top of.
