Stuck inside a rectangular concrete box that smells of dog urine and misery is the situation Mr. Weir and his team of irregulars have found themselves in after a full-on nuclear war.

Eventually the day will come when Mr. Weir and his squad must venture out into what is now reality, and if they make one mistake out there, it could very well alter their lives.
