Fall season in the Arctic means the final preparation is in full swing for the long winter months ahead. In Kavik, Sue sets off on a quest for food to survive the coming freeze. In Eagle, Andy and Kate race to get their fish wheel turning before the chum salmon run hits. With their annual caribou hunt on the horizon, the Hailstones build a cache to store their meat for the season. And in Chandalar, Glenn sets out on the most critical hunt of his year as he hopes to harvest a moose that will yield nearly six months' worth of meat.
