Plot
The Freeling family has sent Carol Anne away from her native California to live with Diane's wealthy sister Pat and her husband Bruce Gardner in Chicago. Carol Anne has been told she is living with her aunt and uncle temporarily to attend a unique school for gifted children with emotional problems, though Pat thinks it is because Steven and Diane just wanted Carol Anne out of their house. Pat and Bruce are unaware of the events that the Freeling family had endured in the previous two films, only noting that Steven was involved in a bad land deal. Along with Donna, Bruce's daughter from his previous marriage, they live in the John Hancock Center of which Bruce is the manager.
Carol Anne has been made to discuss her experiences by her teacher/psychiatrist, Dr. Seaton, who believes she is delusional. The constant discussion enables the evil spirit of Rev. Henry Kane to locate Carol Anne and bring him back from the limbo he was sent during his previous encounter with her. Kane drains the high rise of heat and begins appearing in mirrors. Not believing in ghosts, Dr. Seaton has come to the conclusion that Carol Anne is a manipulative child with the ability to perform mass hypnosis, making people believe they were attacked by ghosts. Also during this period, Tangina Barrons realizes that Kane has found Carol Anne and travels cross-country to protect her.
