The Enterprise's sensor readings indicate a planet unsuitable for any carbon-based life at the level of a developed civilization. Suddenly they get an apparition in space from someone who looks like and claims to be Abraham Lincoln. He insists on them checking him out and coming over to a small part on the planet surface (which has suddenly developed a perfect atmosphere for humans). He is received with full presidential honors and Kirk and Spock agree to beam down with him, but as they do, phasers and tricorders fail to dematerialize with them, and communicators won't work. There they meet Surak, the greatest Vulcan of all time, equally convincing. The quartet is greeted by a creature consisting of molten rock who presents them to notorious historical villains Ghengis Khan, Colonel Green, Zora and the Klingon Kahless the Unforgettable.

Abraham Lincoln: [interrupting] What a charming negress. Oh, forgive me, my dear. I know that in my time some use that term as a description of property.
Uhura: But why should I object to that term, sir? You see, in our century, we've learned not to fear words.

Giants from history
30 August 2014 | by bkoganbingSee all my reviews

This episode shows how truly tired the Star Trek writers were getting. At least twice before William Shatner was captured by aliens and put into combat situations for some gain or amusement of superior aliens. In this one he has Leonard Nimoy for company and a pair of giants from earth and Vulcan history. Lee Bergere and Barry Atwater playing Abraham Lincoln and Surak the founder of Vulcan logic philosophy.

Some volcanic rock creatures with some amazing powers have decided to see what the concepts of good and evil are all about. They also recreate four people who are considered villains in universal history.

Really though, to make this truly even as it seems only contemporary good had anything to lose I would have had two people defined as evil in the Star Trek world also competing. That would have made it more interesting.

Star Trek prime was grinding to a halt and this is why.
