First Activation

Harry and his brother Jack are on an airline flight, headed for a wild weekend a ritual they have enjoyed every May since leaving the army. The trip takes a terrifying turn when they land in New York to find that JFK airport is almost deserted and that the few ground crew they can spot have all been brutally slaughtered. Is it a terrorist attack? Or something even more menacing? When a security guard appears and offers to help the passengers, but promptly shoots the first person off the plane and then kills himself, Harry realises that there is something very, very wrong in New York City.
