The Enterprise transports the Medusan Ambassador Kollos; his telepathic interpreter, Dr Miranda Jones; and Engineer Laurence Marvick. Only Vulcans and those trained in Vulcan self-control can handle the horrible sight of a Medusan (and then only with eye protection). Attempting to kill Kollos, Marvick (jealous of Miranda's interest in Kollos) goes insane at the sight of the Mudasan ambassador. Before dying Marvick, one of the designers of the Enterprise, takes the ship outside the galaxy where it is hopelessly lost. Once it is discovered that Miranda is blind (she had fooled them with a complicated neural sensor in her dress) and cannot guide the Enterprise, Spock mind-melds with the navigationally proficient ambassador who quickly gets the Enterprise back in known galactic space. However, while severing the mind-meld, he forgets the visor, sees Kollos, and goes insane.

Although often cited by some fans as evidence of a "larger message" in Star Trek, the "IDIC" ("Infinite Diversity in Infinite Combinations") medallion that Spock wears during the dinner scene had much baser origins. Leonard Nimoy was originally supposed to give a lengthy speech about the medallion and what it represented. Nimoy found the speech completely out of context in the scene and the episode and refused to say the lines until he got an explanation from producer Gene Roddenberry, who had had the lines and the use of the medallion inserted into the episode. Roddenberry came to the set and admitted to Nimoy that he was selling the "IDIC" medallions through his personal marketing company, Lincoln Enterprises, and inserted the scene about the "IDIC" purely as product placement to generate sales. Nimoy ultimately refused to say the lines, and instead the scene was re-written with Capt. Kirk and other characters commenting on Spock's wearing of the medallion instead. See more
Towards the end of the scene where Kirk and McCoy discuss Miranda, Kirk finishes his drink swallowing the very last drop. The next cut then shows the cup is still quarter full without sufficient time for a re-fill. See more
Captain James T. Kirk
Captain's log, stardate 5630.7. We have been assigned to convey the Medusans' ambassador to the Federation back to their home planet. While the thoughts of the Medusans are the most sublime in the galaxy, their physical appearance is exactly the opposite. They have evolved into a race of beings who are formless, so utterly hideous that the sight of a Medusan brings total madness to any human who sees one.
