The future world has been divided into sectors - each the same as the other. Surrounded by thick steel fences, there is no way in and no way out. Yet a cyborg army penetrates each sector, picking off its citizens one by one, until no one is left. Behind the sectors’ thick walls, the citizens wait to die. Few will be chosen to survive what’s coming; the rest will be left behind to suffer. A new world has been created, and its rulers are incredibly selective on who will become a citizen. They want only those with important roles in society to help create a more perfect future.

The news sends the circus into a panic.
