Dread

An infamous Sanatorium with a bad reputation hidden in the Appalachian mountains. A man who's wrongfully found himself there by the actions of his past. As he begins to witness strange events he cannot explain, he soon realises that the true horrors lie not inside his prison walls; but outside in the woods of the mountain. As time starts running out and danger starts to close in, he will have to fight for his freedom and, ultimately, his survival.
