Captain Kirk leads a landing party from the U.S.S. Enterprise to a Class-M, Earth-like planet, where, as a young lieutenant 13 years ago, Kirk commanded his first planetary survey. When Kirk first visited the planet, the natives were peaceful and primitive, but the landing party finds them now at war with each other, with one side using advanced firearms.
After Commander Spock is shot by one of the natives, the landing party beams back to the Enterprise, and Spock is treated by Dr. M'Benga, who interned at a Vulcan ward.
After the Enterprise detects a Klingon ship in orbit of the planet, Captain Kirk and Dr. McCoy return to the planet to contact Kirk's old friend Tyree, leader of the Hill People. The Hill People are at war with the Villagers, who have been taught to make guns for nearly a year by the Klingon Empire, in violation of its peace treaty with the Federation.
To balance the Klingons' aid to the Villagers, Kirk teaches the Hill People to use firearms as well, but he realizes he has introduced the serpent into the garden of Eden.

Dr. McCoy: "She's dead."
