An outlaw is given immunity to help track down a gang that's been robbing an express line delivery service. Don "Red" Barry, Wally Vernon, Ariel Heath, George Lewis, William Halligan, Hooper Atchley.
Better than usual Barry outing sees him teamed up for the first time with new sidekick Vernon. The plot concerns Barry's efforts to clear himself from a string of stagecoach robberies by exposing the real culprits, the sheriff and a local banker. Fast-paced.
