The Federation starship Voyager is transporting a telepathic race, the Enarans, to their homeworld. Chief Engineer B'Elanna Torres begins experiencing intense dreams in which she is a young Enaran woman named Korenna having a forbidden love affair with an Enaran youth, Dathan. The dreams seem real, more like memories, and they become increasingly disturbing and dangerous, forcing Torres to seek answers from the Enaran passengers.
She learns that her dreams are actual memories being projected to her by one of the visiting Enarans named Korenna, now an old woman. The memories are of a lover of Korenna in her youth, who was a member of the "Regressives", a group that spoke out against technology. The Regressives were deported and executed in a program of mass genocide. The Enarans, though, seek to cover-up the genocide by teaching succeeding generations that the Regressives brought about their own demise.
On Voyager, Torres visits Korenna's quarters, and finds her dying from what she claims is a murder to continue the conspiracy. Before dying, she projects the ending of the story to Torres — how she turned her lover over to the authorities and watched his execution.
Torres confronts the Enarans, but they deny wrongdoing. Though the Prime Directive forbids CaptainJaneway from interfering, she casually remarks that the last of the Enaran engineers are packing their equipment. Torres rushes to engineering, where she confronts an Enaran woman with whom she had become friends and bemoans the fact that she is unable to project the memories, and thus prove their validity. The Enaran tells Torres that she is able to connect their minds--and proceeds to do so with Torres--and the episode closes with the first 'dream' of all, but now the Enaran woman is the main character.
It has been rated as the best third season Voyager episode then produced by the Jammers Reviews web site with a "sensibly written" script and "wonderfully acted" show; its web creator, Jamahl Episcokan, awarded it 3.5/4 stars. Episcokan notes that:
'Star Trek has always been known to venture into social commentary and allegorical content, and with "Remember" the Voyager team comes up with a winner.'
