Damn what a shot. With the huge gap between TMP and TWoK, I'm guessing this must be the 2270's or early 2280's, and yeah, whether the House of Duras or another politically powerful and corrupt House has done something to the detriment of the Empire, the Enterprise has uncovered the 'smoking gun' and been ordered to deliver it to the Klingon High Council and he's been given this escort to make sure it reaches there.
Kirk may actually be thinking a Klingon Civil War wouldn't necessarily be that bad, until Spock probably states this: 'Captain, my Vulcan logic and Human feelings are in agreement that we must not compromise this mission. We may be rivals with the Klingons on most levels, but they still have a citizen populace to look after like we do. A Klingon Civil War will invariably kill millions, possibly billions, of Klingons who have no stake at all in either side of the conflict. Those citizens are who we are doing this for, as well as our own, Jim.'
Probably Kirk has evidence to prove to the Klingon High Command of the perfidy and treachery of the House Clan of Duras in betraying one of the Klingon Colonies near the Klingon Romulan Border and slaughtering them in order to gain more funds and material to further the wealth of the House of Duras at the expense of the Empire...
He just needs the escort to avoid any House Of Duras Birds of Prey from interfering in bringing the evidence in front of the Klingon High Command...
