Star Trek Voyager: Episode 5: Phage

VHS

Neelix directs the crew to a planet supposedly rich in dilithium, but during an away-team survey, he is attacked by a humanoid alien who surgically removes his lungs. Transported to sick bay, Neelix's only hope is a pair of holographic lungs programmed by the Doctor. Janeway heads a search for the aliens, the Vidiians, that leads to an asteroid that serves as a base. When confronted, the aliens admit to stealing Neelix's organs, but defend themselves by telling the story of the "phage," a bizarre disease that attacks their people, eating away at their bodies and organs until they are forced to scavenge others as substitutes. The aliens explain to Janeway that they have already transformed the lungs for their own use, but they agree to help Neelix, and perform an emergency lung transplant with a willing donor, Kes.
