When Sarek returns to Vulcan for Amanda's funeral, he shares his findings with Kirk, Spock, and Dr. Leonard McCoy, and Kirk agrees to take him to Freelan aboard the "Enterprise". The Captain's own plans are to leave the ship to rescue his nephew Peter, a senior cadet at Starfleet Academy who has been kidnapped by the renegade Klingon Kamarag in order to lure Kirk into a trap. Kamarag, acting under the mental influence of the Freelans, is the leader of the renegade Klingons who defy the orders of the female Klingon Chancellor Azetbur. Peter is brought to the Klingon homeworld Qo'noS and placed in the care of Kamarag's niece Valdyr, who believes her uncle's actions are dishonorable but who is bound by her secondary status as a woman to follow his orders. She is impressed by Peter's bravery and strength when he overpowers several Klingon warriors in an attempt to break out, even after five days of starvation. Over the course of Peter's imprisonment, the two fall in love and eventually escape together. As they approach a Klingon spaceport intending to hijack a ship, they meet up with Kirk, Spock, and McCoy, who had intended to rescue the cadet. The five of them manage to steal a miniature Klingon Bird-of-Prey and escape back to the "Enterprise".
