The USS Enterprise under Captain James T. Kirk is sent on a secret mission. Kirk is to take a Klingon warrior named Ksia to the Klingon homeworld. Ksia was once the tutor of the reclusive ceremonial ruler of the Klingon Empire, the Kitumba. But Ksia defected to the Federation in order to prevent the imminent all-out attack of the Klingons on the Federation. This attack was conceived by Malkthon, who is the Klingon Warlord, the actual political ruler of the Empire. Ksia plans to convince the adolescent Kitumba to speak out against the imminent attack as Ksia is convinced that the resulting war would destroy both the Federation and the Klingon Empire.
