Ok, a cult believes this girl will help usher their leader into the world of the living. They were going to sacrifice her as a child but a local cop abducts her and takes her away to safety. She is eventually drawn back to her hometown, thinking she is a girl who went missing many years ago. Involves a big creepy house in a small town with a lot of mirrors. Ends with her being possessed. It’s a newer film and I’ve been wanting to recommend it but cannot remember the title. Thanks in advance!
