Jim, a young squaddie, finds himself locked in an old warehouse in pitch darkness. He has no clue as to where he is or why. The space is empty but for the presence of a stranger – another soldier by the name of Spyro. They are fed rations through the locked door. They follow a regimented daily routine of exercise. As they get to know one another, the cracks begin to show. Jim harbours a terrible secret; civilian deaths weigh on his conscience. Why are they there? Is there a way out? And how long can they keep going?
