As The Frenzy is taking over Chicago, the high school kids have discovered problems of their own. The local high school in Morton Grove has been overrun by a horde of undead teenagers. It is rumored that a zombie cheerleader with hair the color of blood now rules the halls, and she carries a machete to prove it. Detention takes on a whole new meaning at this “Nightmare High”. They say should you find yourself trapped in this schoolhouse of the damned, stay calm, act like the dead, and you may escape unnoticed. If you do, don’t stop for even a moment to look over your shoulder, because if she sees you, there may be some horrid lessons you’ll have to learn.
Chicago is on lockdown as uncovered secrets of the government and a contagion have come together to create panic in the streets. As subway tunnels have become the underground passage of the wary citizens, Morton Grove has been chosen as a lock-down zone to the bandits, rioters, and murderous maniacs unleashed by the chaos. But as the criminals went literally underground, they inadvertently unleashed the souls of the bodies hastily buried there at 8230 Austin Avenue. A gang of delinquents and villains, infested with evil spirits and armed with crude weapons, have become what many Chicagoans call “The Frenzy”. Will you make it through without becoming one of them or will you succumb?
