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

Open a channel, Lieutenant. This is the commander of the U.S.S. Enterprise. All cities and installations on Eminiar 7 have been located, identified, and fed into our fire control system. In one hour and forty-five minutes, the entire inhabited surface of your planet will be destroyed. You have that long to surrender your hostages.
