Having learned to survive the zombie apocalypse in the wilderness of Alaska, a battle-weary cohort is called upon for help in this horror series finale.

A year into the undead apocalypse which has spread across North America and beyond, a group of survivors led by Neil Jordan are still alive against all the odds. Having escaped the horrors of Anchorage, they are still persisting on the Last Frontier, carving out a life for themselves far away from the legions of the dead.

Now they're asked to plunge back into the tempest following a distress call from Anchorage. Having finally established a refuge for themselves, Neil and the others must decide what sacrifice they are willing to make for complete strangers. Will they now return to the very place where they once waited for help in vain?
