Originally Aired: February 6, 1995
In the course of helping to investigate a network of caverns in a planetoid for dilithium deposits, Neelix is attacked by a previously undetected alien and left in a state of shock. He is beamed directly to Sickbay where it is found that his lungs have been teleported out of his body. The Doctor keeps him alive by projecting a pair of holographic lungs into his torso using Sickbay's holographic emitters.
