After one too many successful stick-ups of the Carson City stagecoach by the Champagne Bandits, the local banker decides to build a railroad track through town. To do so, he'll need to employ the help of "Silent" Jeff Kincaid (Randolph Scott), the only man who can tunnel through the mountainous region. Unfortunately, Kincaid has more than just the mountains to deal with -- neither the locals nor the Champagne Bandits are happy about the new railway.
