This is the theatrical trailer for the 1986 supernatural horror feature "Poltergeist II: The Other Side", the second entry in the Poltergeist media franchise and the first sequel to the 1982 Steven Spielberg/Tobe Hooper classic "Poltergeist".
Directed by Brian Gibson, the movie was released though MGM/UA Entertainment Company on May 23, 1986.
One year after the events of the first movie, the Cuesta Verde neighborhood has been turned into an archaeological dig centered around the spot where the Freelings' home stood. The excavation leads to the discovery of a cave by a ground crew. Its existence is revealed to psychic Tangina Barrons (Zelda Rubinstein), who informs her friend Taylor (Will Sampson), a Native American shaman. After investigating the cave for himself, Taylor realizes that the spirit of Rev. Henry Kane (Julian Beck), a deceased, insane preacher, whom he has seen in dreams is after Carol Anne (Heather O'Rourke) and goes to defend her.
The Freeling family have relocated to Phoenix, Arizona, and now live in a house with Diane's mother, Jess (Geraldine Fitzgerald). Grandma Jess is highly clairvoyant, and believes that Diane (Jobeth Williams) and Carol Anne possess the same abilities. Jess later dies from natural causes, but not before telling Diane one last time that she'll always "be there" if she needs her.
Taylor shows up as Kane begins his first assault on the home. Unable to get in through the television as the family has removed all television sets from the home, Kane's minions are forced to find another way in, this time through Carol Anne's toy telephone. The attack fails, and the family gets out of the house quickly. Taylor introduces himself and convinces them that running would be a waste of time since Kane would only find them again, and they return to the house.
Kane himself shows up at the home one day in human form and demands to be let in, but Steven (Craig T. Nelson) refuses. Taylor congratulates him for resisting Kane, and then takes Steven to the desert and gives him the "Power of Smoke", a Native spirit that can repel Kane. Tangina shows up at the house and helps Diane to understand Kane's history and how he became the Beast that is now stalking the family. She also points out that Diane is unique in that she is one of the only people on earth who have been to the spirit world while living. Diane has visions of Kane in the mid 19th century, when he was the head of an apocalyptic cult. Kane led his followers through the desert and into the cave, because he believed that the end of the world was coming, but then kept them trapped and captive there to slowly die with him after the day of his prediction came and went. Because he was so deranged and evil, Kane became a monster after death, and controls the souls of his followers. Taylor warns the family that Kane is extremely clever and will try to tear them apart.
With Taylor having left, the family's morale drops. Steven lets his guard down and gets drunk, swallowing a Mezcal worm that is possessed by Kane, who then temporarily possesses him. The possessed Steven tries to rape Diane, who cries out that she loves him, weakening Kane's hold. Steven then vomits up the worm possessed by Kane, which grows into a huge, tentacled monstrosity. In this form, Kane attacks Steven from the ceiling, but Steven uses the smoke spirit to send him away. The Beast launches another assault before the family flees. The Freelings decide to confront the Beast on his own turf, the Other Side.
The Freelings return to Cuesta Verde and, with Tangina, enter the cavern below their former home, where Kane pulls Diane and Carol Anne over into the Other Side. Steven and Robbie jump in after them through a fire started by Taylor. On the Other Side, which appears as a place of floating limbos without sense of direction, Steven, Diane, Robbie, and Carol Anne unite, but the now monstrously transformed Kane grabs Carol Anne and begins to drain her life force, but she is saved after Taylor gets a charmed Native spear into Steven's hands, and he stabs Kane with it, defeating the monster. Carol Anne nearly crosses over into the afterlife, but Jess' spirit appears and returns her to the family. The Freelings then return safely and thank Taylor and Tangina.
Steven gives the family car to Taylor, after he had expressed an affection for it previously, and Taylor drives away with Tangina. After the Freelings realize that they now have no ride home, they chase after Taylor.
