The Cosmic Cavemen

Summary
Stardate 2314.6: The USS Enterprise is orbiting the newly-discovered planet Neesan, when Spock discovers life-forms on the planet. The life-forms are at the Stone Age level of development and Captain Kirk orders that the crew observe the Prime Directive and not interfere in their culture. Kirk decides to lead a landing party down to the surface to quietly observe the inhabitants.

On arrival on the surface, the party is attacked by primitive men riding pterodactyls and carrying spears. After a brief fight with the primitives, Kirk and his party surrender to the men to avoid any unnecessary bloodshed. As Spock calls via communicator to check on the party's progress, it is smashed by a primitive who is frightened by the "spirit voice in a small box".

Kirk and his party are led into a cave system where they are put before Lok the Wise, who tells Kirk that she "saw" the landing party tresspassing on the sacred ground of Unruho using her telepathic abilities. The penalty for tresspassing is death, and they are led to a large stone tower to face the statue of Unruho, and discover that it is the image of Spock. The party attempt to make their escape but are stopped by Queen Lok after she blows Backi tree powder from the local trees that put the party to sleep.
