Don't live in the past. That's what they say. So Jenny's trying. Trying to forget all of the horrible baby-sitting experiences that landed her in the hospital last year. But now Jenny's in a new house. In a new neighborhood. And Jenny's new neighbor, Mrs. Warsaw, wants her to baby-sit. Poor Jenny. If only she could "just say no" to sitting. Because someone is watching Jenny. Waiting for her. Someone who hates baby-sitters. Someone who wants her... dead.
