Because of a feared imminent Cardassian invasion, Vice Admiral Alynna Nechayev comes to the Enterprise on the USS Cairo, to replace Picard as its captain by Cairo's captain, Edward Jellico, who immediately makes his mark on crew and ship, tells Troi there's no time for a 'honeymoon' with either for he expects the negotiations with the Cardassians he's charged with to fail and hastily deploys big plans to prepare the flagship for battle. Meanwhile, Picard, Worf and Dr. Crusher have a top-secret mission, to find and sabotage the presumed biological superweapon which can wipe out all life on a whole system prior to invasion. After their training, the trio bribes a Ferengi smuggler ship to reach the suspected Cardassian planet, but by the time they have intruded the subterranean installation... Written by KGF Vissers

This episode and its concluding part set the scene for Star Trek: Deep Space Nine (1993), as it is revealed that the Cardassians have left the Bajoran sector. Indeed, the writer, Ronald D. Moore, became a senior writer on DS9 after TNG ended. See more »

Gul Lemec: [sitting in the Enterprise's Observation Lounge displeased when Jellico suddenly walks in, followed by Riker and Troi; he gets to his feet] What is going on? I've been waiting here for over an hour...
Captain Edward Jellico: [talking over him] I'm Captain Jellico. I believe you know Commander Riker and this is Lt Commander Troi. Let's get to it, shall we?
Gul Lemec: [with great disdain] This treatment is a deliberate insult to the Cardassian Union! I have been kept waiting here for over an hour!
Captain Edward Jellico: Then I'm sure you're ready to talk.
Gul Lemec: [...]

Exemplary guest stars

Picard, Dr. Crusher and Worf as a strike team? Even though the mission is eventually justified, I've always thought these were unlikely candidates for a stealth job. What it really does is sideline the captain of the Enterprise for an abrasive replacement (Ronny Cox), someone who runs counter to everything that makes the ship run smoothly (almost an affirmation of the writers' need to shake things up on an long-running show), and that just makes for good drama; we want this guy to take a hike and get the ship back on a smooth course.

But this episode exists almost purely as setup for Part II, and to that end, the best scene is saved for last. David Warner is that classic psychotic interrogator, one who deals in mental warfare more than anything.

He is ideal for the dark hour that's to come.
