Calvary Gaol, standing bleak and forbidding on the Cumbrian hillside, exerts a curious influence over Georgina Grey. Her family's history is closely bound up in the penitentiary’s dark and terrible past. Television presenter Chad Ingram is fascinated by Calvary as well. He plans to conduct a new experiment in the long-vacant structure within the brooding desolation of the old execution chamber. Chad's experiment and Georgina's curiosity, however, will have horrifying consequences. Someone is dead set on suppressing the truth of Calvary, and is willing to go to any lengths to ensure that its shocking past remains buried.
