Because of Anna's tough past, she can't help but feel unworthy of the wonderful life she has now. The day they move out, Anna sends her family off as she finishes things up at the rental house. Just as she tries to leave, the spirit of a deranged Nun stuck in purgatory, Sister Catherine, wants Anna's spirit to stay in the house with her.
