 In this world, there is real evil. It lurks in the darkest shadows, as well as the most unassuming places. It wears many masks, to deceive us and ultimately to destroy us. When Bonnie and her family buy a 19th century farmhouse in rural Connecticut, they sense that they are being watched. After two of the children are physically attacked by unseen entities, the family contacts a world-renown team of psychic investigators - to find out what they are living with, and what it wants from them. As the strange occurrences become increasingly violent, Bonnie develops a psychic connection with someone from the past, and investigators witness the escalation of the haunting from obsession to possession.
