In the most remote parts of Alaska, businesses such as canneries and hunting lodges operate seasonally. Each winter these businesses in the remote wilds shut down and hire "winter watchmen" to defend their properties against man, beast and the elements. Now for the first time, four pairs of amateur survivalists have signed on for a unique social experiment, based on the job of a real Winter Watchman. They'll be brought in to see if they can survive the harshest winter of their lives while protecting four respective lodges in the far reaches of Alaska. Can each duo make it to the spring thaw and collect a cash bonus? Or will extreme weather, isolation and fear of man-eating bears compel them to tap out?
