The Duke battles men and mountains to build a railroad.

To movie fans, John Wayne tamed the West and won World War II - almost single-handedly. So he's a natural to blast his way through the Andes as a bold, bare-knuckled railroad honcho.
A tumultuous love story (with co-star Laraine Day), a dynamite supporting cast, horizon-spanning location filming and brilliant Technicolor make Tycoon exciting entertainment. But the biggest thrill is watching Wayne go mano-a-mountain with a ruthless adversary called Mother Nature. the action peaks high above an Andean gorge in a breathless grand finale that involves a half-built bridge, an onrushing wall of water, and a locomotive with the Duke at the controls. Trouble ahead!
