An unholy power in the hands of a religious fanatic!

Thomas Griffin has heard the legends about Strangeways Federal Penitentiary -- tall tales and whispered rumors.

Ghost stories.

Now a guard has died, and the FBI agent is summoned to the century-old prison to investigate.

Inside the massive stone walls, Griffin finds a madhouse. Inmates with more influence than their warders. Guards who break the law in service of greed and envy. And the greatest threat -- not just to body, but to soul -- the disciples of an ancient, blood-thirsty god.
