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.
In the film, a family of five known as the Freelings lives in idyllic suburbia – or so they think. Strange things begin to occur in the house shortly after their cherubic 5-year-old daughter (Heather O’Rourke) begins receiving communication from someone she refers to as the “TV people” through the static on their television set. Their pet bird dies, furniture begins to move on its own, and other such oddities, but things take a turn for the deadly for the family when the tree outside their home seemingly becomes animated and threatens to engulf the middle child (Oliver Robins) into its wooden maw. The boy is saved, but their young daughter ends up missing, ostensibly stolen into another dimension by forces unknown, although she is able to still communicate through the television. The family enlists the services of a group of parapsychologists to investigate the strange phenomena, and hopefully get back their beloved daughter, but the forces that currently dominate the house prove to be much stronger than anything they’ve ever seen before. Tobe Hooper directs this Steven Spielberg production.
