 In 2006, in Red River, Tennessee, a teenager has frequent nightmares. Her mother reads an old letter from 1817 written by her ancestor, Lucy Bell. After a dispute of lands judged by the church, her husband John Bell is cursed by his opponent Kathe Batts, who has a fame of being a witch. From this moment on, an entity threatens John and her daughter Betsy Bell, attacking the girl during the nights. With the support of Betsy s school teacher Richard Powell, who tries to find rational explanations for the manifestation; her brother John Bell Jr.; and their friend James Johnston, who unsuccessfully tries to exorcize the entity from the house, the family does their best to protect Betsy in the haunted house.
