Diplomatic Implausibility: Star Trek The Next Generation: Tng#61

In the aftermath of the Dominion War, the Klingon cruiser IKS Gorkon is on its way back to the homeworld when it is diverted by a distress call... It is two hundred years since the expanding Klingon Empire discovered an icy planet rich in a valuable mineral, topaline. They named the planet 'taD' - Klingon for 'frozen' - and called its people 'jeghpu'wl' - conquered. It is four years since the Klingon Empire invaded Cardassia, breaching the Khitomer Accords and causing a diplomatic rift with the Federation. On taD, depleted Klingon forces were overthown in a coup d'etat, and the victorious rebels took advantage of the disruption to appeal for recognition to the Federation. Now the Klingons have returned to taD and re-established their control. But the stubborn rebels insist on Federation recognition. A solution to the impasse must be a task that falls to the Federation's new ambassador to the Klingon Empire. Worf regards himself as a fighter, not a diplomat. But the Federation disagrees. Now, for the sake of the Empire, Worf must somehow forge a peace between the hardened rebels and the battle-hungry Klingon forces. And as everyone knows, Klingons do not negotiate...
