The battle of the Butte, 1877.
As swirling snows fall from a leaden sky and a deadly winter approaches, two bitter enemies meet in a season of savage vengence. Scout Seamus Donegan--wondering whether he will ever return to Fort Laramie and the warm embrace of his wife and newborn son--is now under the command of Colonel Nelson A. Miles, who pushes his war-weary troops up the Tongue River into butte country. There, amid the rugged, snow-covered bluffs awaits Crazy Horse with a fighting force of Lakota braves one thousand strong. Gathering in the high, cold canyons, these courageous warriors prepare to engage Colonel Miles and the Fifth U.S. Infantry...one last chance for the proud Lakota to shape their own destiny, the last battle Crazy Horse will ever fight against the white man's army.
