A family moves into an old mansion on Long Island's south shore. Strange accidents begin occurring, which a neighbor attributes to the mansion's ghost, Jacob Armand. Jacob claims to be protecting the wife, Melanie, from her husband and kids. The family discovers Jacob has killed before to protect past women he was obsessed with. After Jacob tries to kill Melanie's friend Janice, the souls of his past victims appear and drag Jacob and Lydia's soul, now possessing Melanie, down to hell. Families who lived in the mansion after also experienced unexplained events, showing Jacob's spirit was still causing harm.
