From the minute that Jenny accepts the Hagen baby-sitting job, she knows she has made a terrible mistake. First there is the dark and gloomy Hagen house, filling her with dread and horror. Then the crank phone calls start. When she finds a threatening note in her bag, she realizes that this isn't a harmless game.

He's back. Jenny’s last baby-sitting job nearly killed her—for real. But she's a survivor. She's getting over it. The crazy guy who was after her is gone. She's even got a new baby-sitting job. Then the phone rings. When she answers, she hears a familiar voice. A voice from the past... from the grave... “Hi, Babes, I'm back.”

Jenny just wants to forget the man who murdered all the baby-sitters. The man who almost murdered her. He's dead now. And Jenny's gone to visit her cousin Debra. But Debra has a baby-sitting job. And now she's getting those phone calls, too. Just like the ones Jenny used to get: Hi, Babes. I'm back. Company's coming...

Don't live in the past, they say. And Jenny's trying to forget all of the horrible baby-sitting experiences that landed her in the hospital last year. Now Jenny lives in a new neighborhood, and the neighbor has asked her to baby-sit. If only she could say no. Because someone is watching Jenny—someone who hates baby-sitters.

And there is a strange man lurking just outside. Someone knows that Jenny is baby-sitting. He knows that the baby is asleep. That Jenny is all alone. And now he's coming for her.

From her first job at the Hagen house to all the other baby-sitting jobs she takes, Jenny is haunted by someone strange, evil, calling her on the phone...trying to scare her...to death.
