Director Joseph Kane (King of the Pecos, Dakota) teams up again with John Wayne as a federal agent determined to break up the corrupt Wyoming-territory political machine run by Charles K. Plummer (Harry Woods). Plummer is a politician by day and the head of a corrupt vigilante army by night, bent on killing anyone who opposes his reign. George "Gabby" Hayes co-stars as Major Carter, a newspaper editor in town with his lovely daughter (Ann Rutherford) to cover the eventual election for the statehood of Wyoming. This action-packed western also features Al Bridge (The New Frontier) as Plummer's top henchman.
