Ahh, another good Doctor episode and one of the more innovative story lines in the second season. Voyager encounters a planet that has gone through a ecological disaster leaving the five, yes, FIVE survivors in stasis pods. However, two of them are dead and according to the information from the pods all of them should have been released years ago. A couple of Voyager crew take the places of the dead and get inside the machine which turns out to be a virtual reality simulation where things have gone very, very wrong and the Voyager crew are now trapped as well. Fear not, the Doctor comes to the rescue again, going into the VR simulation to investigate.
