In the midst of some friendly horseplay on their "Flying R" ranch, the Range Busters, Crash Corrigan, Dusty King and Alibi Terhune, are sobered by the arrival of a buckboard bearing their old friend Larry Meadows and his niece Dorrie Willard. Meadows seeks their aid against a gang of outlaws terrorizing his town. Ernie Willard, Dorrie's brother, has been taken in by Tex Laughlin who is using the Willard ranch as an undercover for his real occupation as a member of a gang of outlaws led by Tim Douglas, a supposed friend of the Willards.
