The Enterprise is observing a celestial anomaly, something akin to a wormhole when a starship appears having traveled through it. To everyone's surprise, the ship is an earlier version of the Enterprise, the Enterprise-C commanded by Captain Rachel Garrett. The instant the Enterprise-C arrives however, history is changed. Captain Picard and his Enterprise are battle weary with the Federation having been at war with the Klingon Empire for 20 years. Lt. Tasha Yar is alive with Lt. Worf nowhere to be found. Guinan knows something is wrong and Picard realizes that the Enterprise-C must return to its own time and place if their time line is to be restored. Written by garykmcd

Did You Know?


Several times Riker mentions battling and traveling to Archer 4. Years later, Captain Jonathan Archer was the central character of Star Trek: Enterprise (2001), set over 200 years before TNG. Archer 4 may be named after Captain Archer, Captain of the very first Enterprise. It's unknown if the writers of "Enterprise" chose this name on purpose, or if it's a coincidence. See more »


After taking Tasha Yar's order, Guinan never returns with it. As she leaves Guinan can be seen, apparently waiting tables. See more »


Capt. Picard: The war is going very badly for the Federation, far worse than is generally known. Starfleet Command believes that defeat is inevitable. Within six months, we may have no choice but to surrender.
Capt. Rachel Garrett: Are you saying that all this may be a result of our arrival here?
Capt. Picard: One more ship will make no difference in the here and now, but twenty-two years ago, one ship could have stopped this war before it started.

Excellent television
7 January 2017 | by Mr-FusionSee all my reviews

Star Trek is no stranger to time travel stories (and I have to confess to a certain weariness towards the gimmick, at this point), but with 'Yesterday's Enterprise', they really hit on something special. The technical side of it involves a temporal rift, a Galaxy-class starship from the past, and an alternate universe (not to mention a more battle-oriented Enterprise-D, for which the color blue is very flattering); but it's the human drama that lends this episode its real emotional weight. Should Picard send the travelers back to their own time (and certain death) or keep them alive and hope the war with the Klingons will finally go their way? Mixed up in all of this is Tasha Yar - and I have to say, her presence isn't just a plot device, but an organic way for the writers to make up for her senseless exit in the first season. It just works, and it's really something to see it pulled off so well.

This is classic TNG all the way; big ethical issues, well-drawn characters and powerful storytelling; even Shooter McGavin gets to play a pretty solid character. And for me, one of the series' greatest moments is Picard's utterance of this line:

"Let's make sure history never forgets... the name... Enterprise."
