The Klingon moon Praxis explodes, crippling Klingon resources and dealing catastrophic damage to the atmosphere of Quonos. Faced with the need to redirect resources away from military endeavors, the Klingons – led by Chancellor Gorkon – sue for peace with the Federation. The Enterprise, with her senior-most officers – James Kirk, Spock, Leonard McCoy, and Montgomery Scott – due to retire from space duty, is assigned to escort the chancellor’s vessel to Earth. During the voyage, the chancellor is assassinated. Kirk and McCoy are arrested, tried, and convicted of the crime, and are sentenced to permanent exile on Rura Penthe. They are subsequently rescued, and – with the assistance of Captain Sulu and the crew of the Excelsior – expose a conspiracy to derail the peace process at the conference site on Khitomer. All charges are dropped, and a period of detente between the Federation and the Klingon Empire begins. [“Star Trek VI: The Undiscovered Country” (Dialog of Dr. McCoy’s tells us how long he has served aboard the Enterprise (27 years), allowing us to derive the approximate date of this film.)]
Amanda Grayson Sarek dies at the age of 93. [Sarek]
A Romulan plot to disrupt the detente between the Federation and the Klingon Empire is exposed and foiled by Ambassador Sarek and the crew of the Enterprise. The planet Freelan is revealed to be populated by Romulans and the offspring of captured Vulcans. Those Vulcans who wish to return to the Federation are permitted to do so.

Fleet Admiral Smillie is succeeded by Fleet Admiral Androvar Drake as Starfleet Commander. Captain James Kirk, having been approached by a young woman seeking assistance for her homeworld of Chal, falls in love and resigns from Starfleet. The government of Chal requests, and is given, the Enterprise-A, and the Chal government gives the ship to Kirk, who proceeds to Chal. Drake, enlisting the aid of Captain Sulu, the Excelsior, and the rest of the former Enterprise senior officers, pursues Kirk, whom he charges with acting against the Federation. It is subsequently discovered that Chal was an experimental colony of Klingon-Romulan hybrids developed to survive a feared war with the Federation, resulting in a genetic structure that could retard the aging process. It is also discovered that Drake is a member of the same conspiracy as former Fleet Admiral Cartwright, and intends to sabotage the Federation-Klingon peace process. In the incident’s culminating battle, the Enterprise-A is destroyed (though its crew are all rescued by the Excelsior) and Drake is killed. Chal is saved for its people. Kirk returns to Earth.

The Falorians, seeking Federation admission, donate a planet in the Besar Star System for colonization, and an expedition led by a nephew of James T. Kirk embarks to set up a colony on the planet, named Sanctuary. Captains Kirk and Scott and Commander Chekov join the expedition as advisors. The colony planet is subsequently revealed to be a staging point for the use of a weapon by the Falorians against the Federation, as an outgrowth of their ancient conflict with the Huanni, who have recently joined the Federation. The threat is averted, and the Federation assists in beginning negotiations between the Huanni and Falorians. The Sanctuary colony project itself is a loss, however. [The Last Roundup]

During a diplomatic mission of the USS Chesapeake to the Theta Eridani system, after the discovery that the Darvash, a race seeking Federation membership, was suppressing an insurrection from another sentient species not known to be in the system, the landing party is attacked and the ship’s captain killed. The helm officer of the Chesapeake, Lieutenant Tessa Niles, utilized the slingshot effect to send the ship back in time several weeks to attempt to divert their earlier selves and alter history, then return to the present. The results led to a nuclear conflict on Theta Eridani V and forced the Chesapeake (delayed in arrival at the system by a false distress call from the time travelling ship) to engage and destroy its time-traveling ‘duplicate’.
