Negotiations with the Klingon Empire are on the verge of breaking down, so Starfleet Command orders the U.S.S. Enterprise to prevent the Klingons from setting up a base on Organia, a Class-M planet in the disputed area. Organia is inhabited by peaceful humanoids, Class D-minus on Richter's scale of culture. En route to Organia, the Enterprise destroys an attacking Klingon ship, and Starfleet Command issues a Code 1 all-points relay, indicating a state of war.
Captain Kirk and Commander Spock try to warn the primitive Organians about the Klingons, but the Organian elders insist that they are in no danger and do not need the Federation's help.
A fleet of Klingon ships arrives, and Klingon Commander Kor declares himself the military governor of Organia. Kirk poses as an Organian citizen, and Spock tells the Klingons he is a Vulcan dealer in kevoss and trilium, but Kor eventually learns their true identities and arrests them. The Organians help Kirk and Spock escape, but will not participate in any violence against the Klingons.
When the Federation fleet arrives, all weapons in the fleet and on the planet become inoperable, and the Organians reveal that they are energy beings millions of years more advanced, maintaining a humanoid appearance only for the sake of visitors. The Organians warn the Federation and the Klingon Empire that if hostilities continue, they will disable all ships in both fleets.
Captain Kirk and Commander Kor leave Organia with their fleets, both disappointed that there will be no war.
Factoid: No one on Organia has died for thousands of years.
Factoid: The Organians foresee that in the future, Klingons and the Federation will become fast friends and work together.
Kirk: "I'm a soldier, not a diplomat."
