Plot: 

A married couple and their three young adult children, a son and two daughters, live in a large compound with a garden and a swimming pool. A tall fence surrounds the property and the children have never been on the other side of it, for their parents have kept them unaware of the outside world, even of the existence of the telephone. They are taught different meanings for everyday words. For example, they are told that a "zombie" is "a small yellow flower," and that "sea" is a chair. The parents promise that each child will be ready to venture outside the compound once she or he has lost a dogtooth. Although the children are told they have a brother just on the other side of the barrier, he never appears.
