The year is 3000...something. No one knows the exact year anymore after nuclear fallout destroyed 90% of the world's population 500 years ago. It wasn't until ten years ago an eccentric old scientist created nanotechnology that allowed survivors to live outside safe zones in the harsh conditions that pervaded the Earth.
