The U.S.S. Enterprise is assigned to convey the Medusan ambassador to the Federation back to his home planet, whose formless inhabitants are so hideous that the sight of one can bring total madness to any human who sees one. Medusan Ambassador Kollos travels in a sealed metal container so that no humanoids will see him, and is accompanied by Dr. Miranda Jones, a human woman with telepathic abilities.
Laurence Marvick, an engineer accompanying Ambassador Kollos and Dr. Jones, is in love with Dr. Jones and tries to kill Kollos so she will not leave with the ambassador, but when he sees Ambassador Kollos, Marvick goes insane and takes over the Enterprise engine controls, sending the starship into unknown space outside the Galaxy before he dies.
In order to get back to their own Galaxy, Spock must perform a mind meld with the Medusan ambassador -- whose race possesses superior navigation skills.
Factoid: Dr. Miranda Jones studied on Vulcan to control her telepathic abilities.
Dr. McCoy: "He's dead, Jim."
