She attends a school for gifted children with emotional challenges, overseen by a skeptical psychiatrist, Dr. Seaton (Richard Fire), who believes her claims of past hauntings are delusions. However, the malevolent Reverend Henry Kane tracks her to the skyscraper, using the building's mirrors and reflective glass surfaces as portals to the spirit world.
