This beautifully photographed western was filmed in Argentina amidst the Andes Mountains. Calhoun is a fugitive who flees from a stint in the army, in which he served as an alternative to a prison stay. He and a gang of outlaws make it tough on a railroad that cuts through the Pampas,
causing a railroad policeman--Calhoun's former commanding officer, Boone--to give chase. In the finale Calhoun promises to clean up his act and in return Boone grants him his freedom.
