A high-country train trek turns into a blizzard-bound trainwreck-from-hell for Roamer as a gang of gunmen run roughshod on the rails. They blow the safe, abscond with a mysterious young woman, and torch the train, leaving passengers to burn in the midst of a blizzard. Trailing death in its wake, the gang heads to the high country with Roamer dogging them on foot, the only man bold enough to track them-until he's joined by his cantankerous old mentor, tough-as-nails mountain man Maple Jack. The men converge on the gang in the maw of a fresh and vicious blizzard that unleashes its merciless might. With righteous rage and hard justice their only allies, Roamer and Maple Jack prepare for a final showdown at . . . Timberline.
