The Enterprise gets a distress message and arrives at an uncharted planet rich in kironide, a high-energy source. Kirk, McCoy, and Spock beam down and find a Greek temple where they are greeted by a dwarf, Alexander. He brings them to the ruler, Parmen, who is suffering from an infection brought on by a scratch on his leg. His wife Philana explains that they came from a distant planet and visited Earth during its ancient Greek period, and adopted the philosophies of Plato. Now they have incredible telekinetic abilities, as demonstrated by Parmen when he lashes out in his delirium, threatening even the Enterprise in orbit. Kirk protects Alexander, who is the court jester to the small community and lacks any power. McCoy manages to sedate Parmen before he can kill Alexander...

This episode is believed to feature the first interracial kiss between black and white adult actors in a fictional and scripted context shown on American television.

Leonard Nimoy wrote "Maiden Wine," the song that Spock performs.

The BBC refused to show the episode until 1993 due to what they felt was inappropriate sadistic content.

Episode Quotes
Philana: We married very young. I was only 117 and he was 128.

McCoy: The release of emotion is what keeps us healthy. Emotionally healthy.
Spock: That may be, Doctor. However, I have noted that the healthy release of emotion is very frequently unhealthy for those closest to you.

Dionyd: Too much love is dangerous.
Eraclitus: Cupid's arrow kills Vulcans.

Parmen: Uncontrolled power will turn even saints into savages, and we can all be counted on to live down to our lowest impulses.
Kirk: You're very good at making speeches, Parmen. Just make sure that this one sinks in.
