But Zack’s not letting their hard-fought zombie antidote land in the wrong hands. He’s got a plan to defeat the undead and find the evil genius behind the zombie apocalypse, even if they have to travel cross-country to do it! Time is running out, though, and they’re only halfway there—will Sludgment Day be the dawn of the dead
