In New Mexico’s Cimarron Valley, Kyle Bell and his son Ben scramble to save a herd of bison from a fast approaching winter storm. In North Carolina’s Blue Ridge Mountains, Eustace Conway and his friend Preston brave the wettest winter in decades to stop a dangerous landslide from washing out a rural road. In Montana, Tom Oar prepares himself for the fight of a lifetime after a run in with a pack of wolves while Rich Lewis braves a blizzard to put meat on his table for the winter. And deep in Alaska’s wilderness Marty Meierotto and his family settle into their new remote surroundings.
