Trish is a lonely young girl living on a spaceship with her busy father and mother who is away. She befriends her voice assistant VP, who teaches her about cloning. Trish decides to clone herself to have a companion, and names her clone Clo. At first they have fun together, but Trish grows irritated by Clo copying her. When Clo claims Trish's mother as her own too, Trish plans to dispose of Clo. However, Clo outsmarts Trish and throws her out of the airlock instead, taking her place without anyone knowing the difference.
