The Changeover is a supernatural coming of age thriller based on the young adult novel by Margaret Mahy. The Changeover, set in an earthquake ravaged Christchurch, is about a troubled teenager who must change over and become a witch in order to save her little brother from an ancient spirit.
Laura loses her little brother in earthquake-scarred Christchurch. A decrepit old man marks the child’s hand with a noxious stamp. Jacko sickens quickly while the man grows younger. The doctors insist Jacko needs a bone marrow transplant — and Laura is the only donor. But Laura becomes convinced a mysterious older boy can help her “change over” and become a witch, defeating the evil spirit sucking the life out of her brother.
