Sacrifice

An outbreak of deadly disease. No cure. Everyone who leaves the plague-zone must be shot...At first, the rules were simple: quarantine the city, and let the plague die. So men and women closed their doors, and lived in lockdown, fighting for survival against a disease as contagious and destructive as the Black Death. A disease for which there was no known cure.

But the plague did not die. And so, at lunchtime on a Friday afternoon, the President announces the new rules. Every American should take up arms to protect the disease-free zones. Anyone attempting to leave the plague-zone must be shot.
