The Enterprise tracks the missing Federation's cultural observer, Professor John Gill, to the reportedly primitive and peaceful planet of Ekos. When Kirk and Spock beam down, they find the Ekosians have turned into a Nazi society, with Gill as its Fuhrer, and are at war with the peaceful people of neighboring planet Zeon. They steal uniforms to enter the headquarters; but when Spock is forced to remove his helmet, his ears betray them and they are led straight to the torture chamber. After a flogging as 'Zeon spies,' they manage to escape with the Zeon prisoner Isak, who takes them to the Zeon resistance. The resistance tests them, and plots with an Ekosian defector to get to Gill, posing as a Nazi propaganda film crew. Inside they discover things are not quite as they appear. Written by
Did You Know?
Upon encountering a Nazi officer whom Spock renders unconscious, Kirk misidentifies the man's uniform: "Gestapo, I believe." In fact, the officer was wearing a Totenkopf- or "Death's-head" SS uniform (the Death's Head emblem can clearly be seen on the man's cap), a branch of the SS. Gestapo officers, when in the field, wore civilian clothes. See more
Führer's headquarters reports repulsing an attack by Zeon spacecraft. Our missiles utterly destroyed the enemy.
You look, er, quite well for a man who's been... utterly destroyed, Mr. Spock.
