Poltergeist II: The Other Side seeks to give more back story to the events of the first film, why the youngest child in the Freeling family had been wanted by the spirits, and the nature of the cult from which the spirits culminated, headed by Reverend Henry Kane (Julian Beck).  Kane manifests himself in human form in this sequel, tenacious in his pursuit of young Carol Anne (Heather O'Rourke), now moved away with her family in the hope they could start a new life for themselves.  Tangina Barron (Zelda Rubinstein), the paranormal investigator from Poltergeist, sends out a Native American shaman (Will Sampson) to help protect the family once she discovers the hidden cave buried in the ground where Kane and his followers died, knowing that the family will not be able to escape Kane's interest no matter where they might go.  Craig T. Nelson, JoBeth Williams, and Oliver Robins return.
