"Zack McKinley was just another twentysomething pizza delivery boy before he discovered that his pop culture idols are actually the advance team of an alien invasion. Now, encouraged and aided by his (probably insane) uncle, Zack must track them down, one by one, and kill them before the invasion can begin. But the advance team has no intention of letting Zack get in their way, and soon the authorities are hunting for a celebrity serial killer in a pizza delivery jacket!"
