The war between the United Federation of Planets and the Klingons is coming to a head and it looks like the peaceful settlement on the planet Organia is stuck in the middle. Kirk puts Sulu in charge of the Enterprise, reminding him that his duty will be to the ship, not to the landing party consisting of Kirk and Spock. The people of Organia are a peaceful, welcoming bunch, content with their medieval way of life. When Kirk informs them of the war encroaching on their planet, the Organians seem unconcerned. When the Klingons make their grand appearance and start occupying Organia, Kirk and Spock go undercover as traders, hoping to get the drop on the Klingons and drive them out.
