Black Water, a small comfortable town nestled in the shadow of Black Water Mountain, whispers dark legends-stories of a secret colonial-era military prison hidden somewhere within the landscape. Other tales depict the torturous conversion and burning of witches just before the Civil War. They speak of a brutal prison warden and a cruel priest, who even today haunt the wood of the mountain side. Legends are what they have always been, that is until visitors arrive at the Heart House-a homestead on the very top of the mountain and one-time stop on the Underground Railroad. These students, intent on documenting the historical house, stumble upon the root of these terrible legends and the unspeakable horrors of its antiquity. Now this evil stirs, emanating from its sanctuary and seeking revenge against the trespassers and the sleepy town of Black Water below.
