Crooked mail clerk Charles Haney (Emmet Lynn), coveting his boss' stagecoach line, tips off a gang of outlaws whenever a new gold shipment is due. Hero Dave Gregory (Don "Red" Barry) suspects that the subsequent rash of the stage holdups are the work of an "inside" man, but he can't prove it. Dave takes a job as a stagecoach driver in hopes of flushing out the bad guys. That's just what happens, but not without the aid of reformed gambler Griff Williams (Robert Kent). With Emmet Lynn playing the bad guy in Stagecoach Express, it's up to Al St. John to provide comedy relief.
