Machinist Mate First Class Jackson Creed, Christy, and Frosty, have been separated from their companions. With no idea how to contact his friends, Marine Sergeant Joel "Cruze" Kelly, and out of supplies and ammo, the three reluctantly join a group who offer a secure and fortified location.
But the new group have done something that shakes Creed to the core, they've captured a shuffler, and plan to find out the ghoul's secrets at any cost. Now a massive horde of Z's is about to descend on the location and no one may be able to escape the coming onslaught.
