In the high rocky mountains, Civil Veteran Marshall Brewster has a vision of wealth and fame. Under the tutelage of a hardened railroad tycoon, Brewster will build a railroad connecting Colorado's booming silver mines to a country starved for wealth--and maybe win himself the hand of a beautiful woman in the process. But as in war, Brewster's plan is soon shattered by the enemy: an angry, proud and desperate tribe of Cheyene warriors, a competing railroad baron and the ruthless, murderous hired guns at his beck and call.
