Jim Vesser and his team of railroading men try to build a rail line through a mountain pass, while a group of less scrupulous construction workers sabotages the entire operation in the hopes that they can get their tracks laid first and get the money from the railroad.
Unfortunately the movie Denver and Rio Grande is not yet available on HBO Max.
