Anthropologist, Dr. Alan Cramer, specially selected a group to join him in the investigation of Middleton Wood, known as the most haunted house in the nation. His study of the supernatural, ghosts, would end in tragedy for all of them. Katherine, the young, naive member of the group became possessed by the house and died when she wrecked her car against the massive oak that had taken other lives before her. Now thirty years later, a group of graduate students from Texas A&M, led by Ph.D. candidate Kevin Spencer and assisted by the same Dr. Cramer, are given permission to return to Middleton Wood and continue the original project. As their investigation begins, they quickly become entangled with the ghostly inhabitants. Complicating things, Katherine's spirit pleads for help to escape the evil house of Samuel Greene. Her entreaty reluctantly brings back Bess to face some long held guilt of her own. Coupled with their efforts to complete the research, their struggle to redeem Katherine's spirit may cost one or more of their lives.
