Plot
Rowley, the Mingo kids, the Champs, and a couple other students advance on Greg after Rowley killed Holly Hills in front of him. Two of Bryce Anderson's goons chase Greg into the school cafeteria, where he ambushes and kills them after they kill the lunch lady. Mrs. Graziano and the rest of the band run after Greg throughout the school as revenge for killing Annabelle, but Greg manages to get Jeffrey Laffley to help him and they take Mrs. Graziano hostage.

Rowley gets most of the school on his side and threatens over the intercom for Greg and Jeffrey to release her, or else he will kill Heather Hills and Angie Steadman. Meckley Mingo finds Greg and tries to free Mrs. Graziano, but he has his face crushed in a book by Alex Aruda, who defects to Greg's side. Alex says that he has kidnap Jamar Law, and that they should get information out of him. Jamar, who's head is stuck in a chair, tells them that they should explode one of the walls and let the infected citizens in to kill their enemies, while they escape on a van. Alex agrees and then decapitates Jamar, much to Greg's shock.

Alex, Greg and Jeffrey head to get supplies for the bomb, but they are ambushed by four Mingo kids looking for revenge, before all four are killed by Betsy Buckles. She takes them to Dennis Denard's hiding spot away from Rowley and discuss their plan. They manage to get enough supplies to build the bomb and head to the roof of the school, where Rowley ambushes them. Betsy and Dennis kill the band students and Mrs. Graziano, who escaped, as well as Randy from the Champs, but the rest of the Champs overpower and kill Betsy.

Jeffrey sacrifices himself to set the bomb off and it explodes, killing him and causing a piece of debris to kill Alex Aruda. Angried at the loss, Greg uses the same piece of debris to brutally murder Rowley. The infected burst into the school and kill some people, before Greg, Heather, Angie, Dennis and his friend Erik Glick drive off in a van, not seeing the helicopters landing on the school.

Later, a group of scientists develop a vaccine against the infection and against death and try it on three of the many bodies recovered in the school, Rowley, Alex Aruda and Albert Sandy. They come back to life and Rowley kills several scientists before proclaiming he is now king of Plainview. They are all then drugged and fall asleep, with a mysterious figure saying this isn't Plainview anymore.
