Synopsis:

No, this is not a prelude to Star Trek Deep Space Nine, this is a unique Klingon story. Special emissary K'Ehleyr joins the Enterprise to stop a Klingon sleeper ship that is carrying a battlecruiser full of Klingons from the past who still think the Empire and the Federation are at war. They must stop them before they wake up and start attacking colonies in the region. Now K'Ehleyr is a special girl. Her and Worf were "lovers" six years ago and have "unfinished business." One night on the holodeck after killing some bad guys in one of Worf's calisthenic programs, he and K'Ehleyr mate. Worf begins the marriage ceremony but K'Ehleyr will have no part of it. Meanwhile, the Klingon ship "awakens" and starts to attack the Enterprise. Worf comes up with an idea on how to resolve the situation. he and K'Ehleyr pose as the captain and first officer of the Enterprise, like how the Klingons won the last Klingon/Federation war and now the two of them coexist and makes the "old" Klingons see that the war is over. K'Ehleyr beams over to the T'Ong and begins the integration of the Klingons to present times. And again, Worf and K'Ehleyr go their separate ways.
