When the Vales family moves to a new neighborhood, they hope the change will help their troubled son, Nathan. His first word in months is “eleven,” but aside from the fact that his eleventh birthday is on 11/11/11, they don’t notice any other coincidences. But after a string of violent deaths in the neighborhood, they start to suspect that their new neighbors are part of a devious cult. And as Nathan’s behavior becomes increasingly bizarre, Jack and Melissa can’t afford to ignore coincidences; they soon learn that Nathan is the gateway to the Apocalypse, and it will happen on his birthday.
