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

This is the episode where Guinan first introduces Worf to what he calls the "warrior" drink - prune juice. See more
When Commander Riker and Lt. Yar are performing repairs on the bridge of the Enterprise-C, Tasha refers to Geordi as Lieutenant. We could assume here that in this time line LaForge had not been promoted to the rank of Lieutenant Commander. However, in later scenes, particularly the Ready Room briefing, it is clear that Geordi is wearing the rank of Lieutenant Commander. See more
