Storyline

The Enterprise is heading for the Epsilon solar system. A suddenly approaching alien ship uses scanners so strong that all crew members including Data lose most of their personal memories, even names and ranks, yet retain their operational and language skills. The external communications are down and computer data banks have been selectively wiped. Some, including the ship's manifest, are altered, so as to make a Commander MacDuff Executive Officer (rather then Riker) and the Enterprise is on a crucial mission in a war the Federation would be conducting for years against the Lysian race. The alien ship has been destroyed, they assume by the Enterprise, although there's no battle damage. While crew members behave differently, failing their normal reference patterns, MacDuff volunteers for a memory therapy Dr. Crusher suggests, so he can pretend for it to fail and press on the attack on the Lysian headquarters, but the war logic doesn't quite add up...

Goofs

In the first scene, where Data is playing chess with Counselor Troi, he uses the contraction "I've": "... particularly since I've already taken both of your rooks." For whatever reason, Data has a reputation for being unable to use verbal contractions. See more »

Quotes

Commander William T. Riker: [explaining Troi's visit in his quarters] We were just discussing the situation we're all in.
Ensign Ro Laren: Hm... good. Because I have a feeling that I used to be the jealous type.

Where's Guinan when you need her?
25 February 2016 | by (United States) – See all my reviews

The Enterprise is struck by some force which causes everyone to forget their identities but not their skills. The information they can retrieve suggests that the Federation is in a long-term war.

With Guinan's intuition (she's been familiar with alternate time lines at least twice thus far in the series), she might have been able to shed some light on what was going on, but I suppose in that case, there wouldn't have been much of an episode. Guinan is completely missing here and Data briefly serves as a bartender.

Still, it's one of the better episodes, a real mystery similar to "Clues" but much better than that episode.
