Subject Six-Eight-Four has spent years in a secret underground facility, experimented on and tortured by “evaluators” and guards attempting to break her silence. After suffering at the hands of these people for months on end, she is taken aback by a new evaluator – one who treats her with kindness and concern. His approach breaks her resolve, and Subject Six-Eight-Four learns more than she ever thought possible about herself, her captors, and their facility.
