When local cowboy Charlie Craig is framed for murder, the Range Busters are called in to discover the identity of the true killer. All signs point to land baron Jack Hammond, who owns much of the local territory. The Range Busters send Alibi to the tavern to find information. Denny and Crash snoop around town and learn Hammond plans to burn down Craig's ranch and steal all of his cattle. The Range Busters must act fast to pin evidence on Hammond and his men and stop them from destroying the Craig family fortune.
This is the last film in the Range Busters series, starring Ray Corrigan as "Crash," Dennis Moore as "Denny" and Max Terhune as "Alibi." Building on the success of The Three Mesquiteers, the prolific trio released 24 films for Monogram Pictures from 1940 to 1943.
