Stardate N.G.   With fuel dwindling to nothing, the U.S.S. Voyager lands on a "demon" planet--so-called because its environment is toxic to human life--to collect from its vast deuterium lode. Both Tom Paris and Harry Kim are suited up in protective gear and sent out to collect the precious deuterium, but return without their protective suits. Instead, it is now the U.S.S. Voyager's environment that is poisonous to them. But who are they are where are the true crewmembers? A new lifeform seems to come to a new evolution thanks to the fleet's DNA.
