In war torn Eastern Europe a young nurse named Carole saves valuable lives as part of a humanitarian aid group. Soon her mission will be over and it will be time to return home. But what seems like a short cut to freedom soon turns into a journey of agonising, torturous pain beyond the human threshold. Pulled from their vehicle by a brutal group of armed, masked assailants, Carole and two of her colleagues are held captive within an isolated, underground bunker. Initially assuming that the kidnapping is politically motivated, the truth is far more horrific than they could possibly imagine. Now Carole’s only mission is to survive. But it’s a living hell where staying alive is one thing, but staying in one piece is another.
