Wet. Freezing. Hopeless. As the Alaskan autumn yields itself to the encroaching threat of winter, Neil, Jerry, Meghan and Emma must fight for themselves and the survival of everyone else in their group, including the children Danny and Jules, against growing masses of flesh-hungry zombies. The undead menace continues to nip at their heels as they retreat down the Seward Highway and venture further into the unforgiving Alaskan wilderness. The horrors of Anchorage festering with prowling ghouls are behind them but now new terrors threaten their every step on their arduous trek. The fiends and that their appetite for human flesh are not the only thing to fear as the new world they all must navigate continues to challenge the one basic instinct to which they are all beholden: to survive.
