A boy preacher named Isaac goes to a town in Nebraska called Gatlin and gets all the children to murder every adult in town. Then, a young couple accidentally hit a child, and they must go to the nearest town to report the murder. However, the nearest town happens to be Gatlin. The town is apparently deserted, before they find two children who go against Isaac's rule. They are soon trapped in Gatlin with the rest of the evil children after them, and their only allies the two rebbellious kids.
