On a mission to establish diplomatic relations at Star Cluster NGC321, Kirk and Spock beam down to planet Eminiar 7 to learn that its inhabitants have been at war with a neighboring planet for over 500 years. They can find no damage nor evidence of destruction but soon learn that their war is essentially a war game, where each planet attacks the other in a computer simulation with the tabulated victims voluntarily surrendering themselves for execution after the fact. When the Enterprise becomes a victim in the computer simulation and ordered destroyed, Kirk decides it's time to show them exactly what war means. Written by

First episode to establish the United Federation of Planets as the principal service to which the Enterprise operated under. In previous episodes, vague and often conflicting references were made to this service. Such references included "Space Command", "Space Central", the "Star Service", and "United Earth Space Probe Agency" (the latter even abbreviated as UESPA, pronounced by Capt. Kirk as "you spah" in the episode Star Trek: Charlie X
(1966)). UESPA would later go on to be the principal service to which the Enterprise NX-01 operated under on Star Trek: Enterprise
(2001), since the Federation would not be established on that series until the final episode. See more
When Spock rescues Ambassador Fox from a disintegration chamber, the door to the chamber is opened. As they back away to destroy it, the door is immediately closed. (Obviously stock footage of the first chamber destruction.) See more
Enterprise, this is Anan 7, first councilman of the High Council of Eminiar. We hold your captain, his party, your ambassador and his party prisoners. Unless you immediately start transportation of all personnel aboard your ship to the surface, the hostages will be killed. You have thirty minutes. I mean it, Captain.
Captain James T. Kirk
All that it means is that I won't be around for the destruction. You heard me give general order 24. That means in two hours the Enterprise will destroy Eminiar 7.
