A modern supernatural horror film that explores the dark side of the human psyche, and the terror in facing up to one's darkest fears. Set in London, England, the film begins with a group of theological students who decide to test their faith by proving the existence of Hell.

Karen, Sarah, and Emma Tunney are all moving to a small town in Pennsylvania where, unknown to them, in 1913, a horrid mine accident trapped dozens of children alive, underground. But there's a problem. They're still alive.
