Stardate 4307.1: A giant space amoeba threatens the entire galaxy.
The Enterprise is en route to investigate the mysterious loss of contact with solar system Gamma 7A, when Spock suddenly receives a stunning psychic bolt. The U.S.S. Intrepid, a starship crewed entirely by Vulcans, has just been completely destroyed. In deep space, the Enterprise then encounters a huge living creature, a gigantic one-celled life form resembling nothing so much as a giant amoeba. The entity is cutting a destructive swath through the galaxy, and is responsible not only for the destruction of the Intrepid, but system Gamma 7A as well. Captain Kirk realizes that his starship may be the only means of stopping the creature before it can end all life in the galaxy — for it is about to reproduce. The Enterprise assumes the role of "antibody" and presses forward to attack. The crew feels the effects of invading the giant intruder as fatigue and depression, and Spock pilots a shuttlecraft into the "heart" of the creature to determine its weakest spot. Just before the creature can replicate, an antimatter charge is fired into the creature's nucleus, killing it. The Vulcan succeeds in returning to the Enterprise as his life-support systems are about to expire.
