Stardate 44664.5: Starfleet officers who were on an away team five years ago investigating a mysterious migration of previous explorers to the planet Tarchannen 3 are beginning to mutate into alien life forms and migrate to the planet themselves. Among them are Lt. Commander Leitjen, visiting the Enterprise, and Geordi La Forge. While Dr. Crusher keeps Leitjen in sick bay when her mutation begins, Geordi’s mutation goes unchecked and, more alien than human, he beams to the surface to join the other members of the away team, who have fully mutated.
