Synopsis: Kristie and her older brother Lew are children living with packs of children in a domed-in city. The city was closed off because the world outside was made uninhabitable by pollution, and all the adults died of a plague. The children are doing their best to survive, but the machines keeping the city running are beginning to fall apart. Kristie dreams of going outside to the wonderful planet she sees in old videos, but everyone knows the outside is deadly now, and of course there's no way out. The predictable conclusion is that she finds a way out and, of course, the planet has recovered to a new Garden of Eden.
