When an old friends family is massacred, legendary mountain man Smoke Jensen hits the vengeance trail. He's soon riding into a bloody Colorado war that has militia cavalry volunteers and Kiowa warriors stalking each other across the territory—matching kill for kill, outrage for outrage.

Defying both sides, Smoke uncovers a sinister conspiracy to set ranchers and Kiowas at each other's throats. It turns out that the war's been cooked up by renegade Jack Tatum and his outlaw band, who stand to reap a fortune in gold by selling illegal guns and whiskey to the Indians.

High atop the Rockies, a blizzard's white hell sets the stage for the final showdown with Tatum's bloody gang, as the mountain man unleashes an avalanche of destruction. Now his enemies are about to learn that the only thing Smoke Jensen sells is death...wholesale.
