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.

When Capt. Picard, Worf, and Dr. Crusher reach the chasm, they realize that the signal they are looking for is at the bottom, which is 500 meters (over 1650 feet) down, and that they will have to use their ropes and climbing equipment to repel down over the edge. The amount of rope that each carry appears to be much too small to equal 500 meters length, and appears to be at most 100 meters length. See more »


Commander William T. Riker: [of Captain Jellico] Well, I'll say this for him - he's sure of himself.

Suspension of disbelief is beyond the norm
18 August 2018 | by ghatbkkSee all my reviews

Let's see...

We're supposed to believe:

Starfleet chooses to send a Ship's Captain, a Ship's Doctor and 1 security officer (even if it is Worf) on a commando raid deep into Cardassian space with no current intelligence and no real idea of a mission. The Federation of a thousand planets can't put together an actual commando force?

Then we have assigning a new Captain to the Enterprise while Picard is away on his raid, despite having a first officer who is well-trained, experienced and has demonstrated numerous times his ability to handle the Enterprise.

Fundamentally, this episode (both parts) is stupid. The script is ridiculous.
