exception

Humans plan to terraform a planet for colonists in cryosleep on a slower-than-light ship by sending copies of Nina, Mack, Oscar, Patty, and Lewis on a faster-than-light terraforming mission. Living creatures cannot survive faster-than-light travel, so when their ship drops into normal space, a system called the Womb 3D-prints bodies for the five, including their memories. However, the Womb malfunctions printing Lewis' body, apparently creating a monster. The others decide to euthanize Lewis and to print another, but Lewis escapes. Nina manages to print another Lewis, anyway. Meanwhile, misprint-Lewis is still quite human. The crew deduces that at least one of them is a saboteur who intends to destroy the mission. Misprint-Lewis and Mack discover that it is Patty, who has used an additional, small Womb in her research lab to print a copy of herself. Ultimately, only Nina survives and lives out her life completing the mission alone.
