It's New Independence Day in Rural Nebraska, five years after the completion of the Freedom Wall, a four-million square foot security blanket that enclosed the United States mainland like a fishbowl.

On this national day of celebration, America's enemies and former allies join forces to decimate the American dream, bombing airports, military bases, taking out infrastructure, and eradicating most of the population.
