Dakota retrieves her son Tony and takes him to her father, Texas Ranger Earl McGraw. Tony, given a revolver by his mother, accidentally shoots himself in the face after being told not to point it at himself. Cherry and El Wray make love in J.T.'s bedroom. Due to a "missing reel", what happens after this is unknown; when the film returns, Sheriff Hague has been shot in the neck by one of his officers, zombies are massing outside the burning Bone Shack and El Wray's true identity is now known to Hague, who is much friendlier towards him. Dakota, Earl, Cherry's former boss Skip, and Tony's crazed babysitter twins arrive at the Bone Shack. With Hague badly injured, the group decides to flee to the Mexican border, before being stopped by a large mass of zombies. Muldoon's men arrive, killing the zombies before arresting the group. Abby tells them that the soldiers are stealing the gas supply because they are infected, constant inhalation of the gas delays mutation. They also learn that a small percentage of the population is immune, suggesting a possible treatment, which is why Muldoon quarantined the survivors.
