With dark winter in full swing, Alaskans face new challenges in sub-zero temperatures. In Eagle, Andy, now living alone in the bush, maintains the snow-covered trails and takes care of the dogs on his own. In Kavik, after a barrage of storms, Sue fixes her generator in order to have electricity throughout camp. In Noorvik, the Hailstones build a new teepee to shelter their growing family for upcoming hunts. And in Wiseman, Erik takes his wife, Martha, hunting for animal hides to supplement their income.
