In the frozen wilderness of Alaska, a cabin is readied for the winter. Jonesy and Lisa, with their loyal dog Lad, have been preparing their home to avoid a repeat of their horrific first year living apart from civilisation. They survived that. They'll survive this. But then the strangers arrive. Two people who are even more desperate to survive, who have clawed their way through hell to reach Jonesy and Lisa, and who will drag them back down there with them. And out in the forest, that other cabin waits for someone to return...
