Zack's life is all good he's rich, he has friends, and yeah all good, but his sister who is a hag. She slept with about more then 10 guys, and her parents don't know. Basally because there never around so, it doesn't bother him either. But his world turns upside down when his sister gets a boyfriend (which is wired because she's never dated anyone longer then a day after 8 grade.) His name is Robby. Something about him isn't quite right, so Zack and his friend try to investigate more and what do they get? That Robby's house is...Hell.
