The Loon

The isolated, maximum security prison for the criminally insane that houses some of the nation’s deadliest, most frightening psychopaths. But when a freak storm cuts off all communications and causes a massive power outage, the prisoners get loose...and find there is nowhere to go. The blizzard rages outside.
The inmates are now in charge and the staff must band together to survive.
And then they all discover that the inmates aren't the most dangerous thing about The Loon. Because below the prison is a secret place. A dark place. A place where a creature of monstrous appetites has been born. And it's very, very hungry....
