Mylene is ordered to eliminate a double agent selling information to the Eastern Bloc at Sneg Pass. Meanwhile, the Zero Zero Organization Committee question her loyalty. Number Zero explains to the worried Committee members how Mylene's family defected to the Western Bloc looking for freedom, but her parents were killed near the border and she was separated from her brother Paul. She was rescued by a Western bloc spy called Nelson, and after growing up in an orphanage, she volunteered to join the Zero Zero Organization and underwent her training and the cybernetization process. Back at Sneg Pass, Mylene discovers that the double agent is Nelson. They both realize that she must kill him, and she does, but later she wonders if she has actually found the freedom in the West that her family wanted.
