Silent Jeff Kincaid (Scott) is a construction engineer hired by Carson City banker William Sloan (Keating) to build a railway line between Carson City and Virginia City, Nevada. Sloan is tired of the stagecoach being constantly robbed but the locals (and the bandits) try to prevent the rail line from going through. The bandits cause a landslide (which results in several deaths) and then steal a shipment of gold bullion until Jeff can set things right.
