For John Stevens it was just another boring day at his boring job; then the world shattered around him. All of a sudden things are a lot more exciting, as terrorists dressed like janitors and armed with assault rifles move along the halls of the factory, brutally murdering anyone they see. The furor reaches a fever pitch when John realizes that the terrorists aren't just there for the sadistic pleasure of killing unarmed civilians. They're looking for something, and don't seem interested in leaving until they find it. Even after he escapes, events conspire to turn his life upside down, and John is forced to acknowledge that nothing will ever be the same again.
