In war-torn Eastern Europe, a world-weary group of mercenaries discover a long-hidden secret in an abandoned WWII bunker. In a seedy bar in a town ravaged by war, mysterious businessman Hunt hires ex-marine D.C. to assemble a crack team of ex-soldiers to protect him on a dangerous journey into no-man s land. To this gang of hardened warriors, battle-worn veterans and borderline criminals killing is just a job - and one they enjoy. Their mission - to scope out an old military bunker.
It should be easy - 48 hours at the most. Lots of cash for little risk, or so he says. Once at the outpost, the men make a horrific discovery that turns their mission on its head - the scene of a bloody and gruesome series of experiments, carried out by the Nazis on their own soldiers during WWII. Amid the carnage, they find something even more disturbing - someone who s still alive. As war rages above ground, and a mysterious enemy emerges from the darkness below, D.C. and his men find themselves trapped in a claustrophobic and terrifying scenario. Their mission is no longer one of safe-guarding - it s one of survival. Together they must discover why Hunt has brought them to the outpost - and what it is that s killing them off, one by one.
