This is a very scary film in the finest traditions of horror, despite being something of a photocopy of Poltergeist,
After some horrible disturbances and spooky faces in the dark a young boy lapses into a coma for no reason. His parents soon realize, with a help of a psychic, that a battle beyond life itself is going on for control of his body.
Some very good special effects and lots of screamy frights make this a great horror night in. The ending is a real kicker.
