The Enterprise traces a virus-like outbreak that seems to be traveling in a direct line across a planetary system. The next planet is home to Kirk's brother Sam, his sister-in-law and their young son. The Enterprise arrives too late however for Sam. They find flying jellyfish-like creatures that attach themselves to humans. They take over the victims nervous system forcing them to bend to their will. Spock finds a weapon to use against the creatures but it leaves him hopelessly blind. Written by

In the beginning scenes on the bridge after Uhura raises Kirk's sister-in-law, Uhura is not sitting at the communications station which places Spock's science station to her left; Spock's station can be seen in the background to her right which would place her at the navigation sub-station which is to the left of the science station. When she loses Aurelen's signal and Kirk walks away, she is now sitting at her correct station to the right of the science station. See more

Incredible. Not only should it have been destroyed by our phasers, it does not even register on my tricorder.
