Olivia Foxworth is gone and Corrine (Heather Graham) is in the mental ward. Brother and sister Cathy (Rachael Carpani) and Christopher (Jason Lewis) are now married living under the surname of Sheffield with Cathy's sons Jory and Bart. A mysterious woman moves into the mansion next door. It's Corrine and she befriends Bart keeping it a secret from Cathy, Christopher and even Jory. She starts poisoning his mind against his parents. Cathy adopts Cindy who lost her mother and has set up three beds in the attic.
This starts off more or less like a horror movie. Corrine is the bogeyman with a mysterious plan against Cathy and Christopher. I would have liked the plan to be better defined and better formulated. The situation should build up until a climatic reveal of Corrine. I haven't read these books and I don't really care about them. Bart starts out too normal to be bent completely out of shape like that. The movie should start him off with a bit of disturbing behavior. I'm not sure how good is the source material. This is better than most other Lifetime movies but it is nowhere near theatrical quality.
