Chicago was supposed to be a refuge. Instead, it's a nightmare filled with monsters. And some of them wear human skin. With half the city walled off, the military maintains an outpost that acts as an oasis amidst all the chaos. But, for Billy Bardem, Travis, and gang, things seem to only go from bad to worse with the arrival of an old foe. When Dr. Castle returns, having unlocked the aliens' psychic abilities, he intends to turn them into telekinetic weapons, using the aliens for his own nefarious purposes. Unable to save the city from Dr. Castle's reign of terror, our heroes escape just as the military launches a campaign to try to retake Chicago. Oblivious to the fact that the aliens have built a hive and have laid thousands of eggs the military may be in over its head and it's up to Billy Bardem, Travis Mahoney, and the cheerleader Sarah Lewis to devise a plan to save both humanity and the aliens--ensuring the survival of all.
