In this creepy flick, a retired horror writer suffering from dementia hires a live-in nurse to care for both her and her Braintree, MA, estate. However, what the writer fails to mention to her new caretaker is that Polly, the fictional protagonist of her most popular novel, The Lady in the Walls, is not actually be fictional, and that she may have been killed in the estate the writer now inhabits.
