Spoiler Warning: In order to rid the town of the children, Alan devises a plan: to detonate a briefcase of explosives inside the children's classroom. By thinking of a brick wall, he is able to create a mental barrier and keep the presence of the bomb a secret from the children. Jill begs him to spare David because he is not like the others, and Alan agrees. He attempts to do this by asking David to leave the classroom to get his notebook from his car. The children begin to suspect that Alan is hiding something, and they slowly "destroy" the wall. Finally, Jill shows up, but the children stop her and attempt to use mind control. David, tired of this, rushes to her defense and knocks Mara over. The children turn on David, but Jill rushes him from the building. As soon as the children discover Alan thinking of the bomb, it detonates, killing everyone inside, along with Alan. Jill and David survive the massacre; she says that they will both move to a place where nobody knows them. David looks off into the distance as they drive away.
