Just before the Civil War (but after the South has seceded), Southern saboteurs try to prevent railroad construction from crossing Kansas to the frontier; army captain Nelson is sent out to oppose them. As the tracks push westward, Nelson must contend with increasingly violent sabotage, while trying to romance the foreman's pretty daughter Barbara.
