In a town ravaged by war, mysterious businessman hires an ex-marine 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 during World War Two. Amid the carnage, they find something even more disturbing - a survivor. As war rages above ground, and a mysterious enemy emerges from the darkness below, the ex-marine 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 what it is killing them off, one by one.—johnnyber
