Red Ryder gets a telegram from his old friend Dan O'Connor asking for help in his fight against Faro Savage and his gang of rustlers. A gun dropped by Faro during a rustling raid makes Red and Sheila O'Connor, Dan's daughter, think they have ample proof against Faro but they are stymied by the law. Buckskin Blodgett and the Duchess, Red's aunt, find the body of O'Connor who was killed when Faro's men sent the sheriff out on a ruse. Sheila, discovered while rifling Faros office for evidence, escapes but not before she is recognized. Faro kills one of his own henchmen and then frames Sheila for the murder. Red and Little Beaver set out to clear Sheila and to try to find evidence against Faro and his gang.
