During a period of rest, and just after three elementary school science fair prize winners leave with Capt. Picard for a tour of the ship, the Enterprise hits a quantum filament, trapping its people in different compartments under varying emergencies. Geordi and Dr. Crusher face a plasma fire that begins to destabilize stored supplies into high-yield explosives; Data and Riker face a lethal electrical arc on their only available route to engineering; Worf presides over Keiko O'Brien going into labor; the wounded captain and the school children rally to escape a damaged and dangling turbolift; Troi, as highest in rank on the bridge, faces a crucial decision as the warp core heads toward collapse and ship-wide destruction.

In trying to understand O'Brien's description of a quantum filament, Troi (unsuccessfully) compares it to a cosmic string, which the Enterprise encountered in "The Loss". See more »


While Picard and the children are on the turbolift leaving the bridge, the movement of the light outside the window reveals they are moving up, rather than down. See more »


Chief Miles O'Brien: [a quantum filament has caused severe damage to the Enterprise, leaving Troi in command of the Bridge] If the containment field strength continues to drop at its present rate, we still have at least two hours before it becomes critical.
Ro Laren: But you're ignoring the fact that the power coupling is also damaged. If that coupling overheats the field strength could drop a lot faster. We could have a containment breach in a matter of minutes.
Counselor Troi: What do you suggest?
Ro Laren: We should separate the saucer now and put ...

Conflict and teamwork put to great use
13 April 2017 | by Mr-FusionSee all my reviews

'Disaster' is by no means a yawner; there is a lot going on here. The ship is broken, the crew is separated throughout the decks and systems go haywire left and right - it's just one crisis piled onto another. And even though there are tense moments, there are also little bits of humor here and there.

It works because the characters (and their players) work well together, even outside of routine. Picard's not good with kids, but he's forced to adapt; Worf isn't a doctor, but Keiko's having that baby regardless; and Troi isn't used to a leadership role, but rank forces her to man the bridge (nice use of Ro as her aggressive adviser). Even the subtle image of the Enterprise adrift, with no power is eerie (we never see the model without its lights on; was not ready for that).

Out of catastrophe, a great episode emerges.
