Part 8/11:
Sarge, the team leader, grapples with the psychological scars from his past experiences in the quarantine zone. The film reveals a heartbreaking backstory of loss and survival; Sarge had to kill his own family once they were turned, a dark moment that haunts him.
Their mission leads them deeper into danger as they navigate the remnants of the quarantine zone, where nearly all their prior knowledge of zombies is outstripped by a new breed engineered by the Judas Project—a zombie named Elvis who commands an army of the undead.
