Captain Kirk and the Klingon commander Kor

While negotiations quickly break down between the Federation and the Klingon Empire, the Enterprise is sent to Organia, a planet of primitive people strategically located between the two sides. Kirk and Spock beam down in an attempt to convince the peaceful Organians to accept Federation aid and protection against the Klingons. When the Klingon forces attack the planet, the Enterprise and the Klingon forces square off to battle in orbit of the planet. Displeased by the outbreak of violence, the Organians reveal themselves to be powerful creatures of pure energy who easily neutralize the weapons on both ships, and force both sides to sign a peace treaty.
