Energy beings from a nebula displace Chakotay's consciousness from his body. The Doctor pronounces him brain-dead and B'Elanna turns to Chakotay's cultural beliefs to try to bring him back. Meanwhile, Chakotay's spirit roams the ship and infiltrates crew members in an attempt to warn his shipmates of the dangers of the nebula, but they mistake his efforts as a malicious alien manipulation.

Did You Know?


First appearance of Captain Janeway's "Ancient English Holonovel," which seems to be a mash-up of Charlotte Brontë's Jane Eyre and Henry James' Turn of the Screw. The latter was also the basis for a previous Star Trek production Star Trek: The Next Generation: Sub Rosa (1994). The Holonovel returns in Star Trek: Voyager: Learning Curve (1995) and Star Trek: Voyager: Persistence Of Vision (1995). See more »


SPOILER: When analyzing the "alien" brainwave that was superimposed on other crew member's brain patterns, the Doctor says that it has an unusual energy signature, which he has never seen before. As established later, this new brainwave actually belonged to Chakotay. It would be rather strange that the Doctor would not have Chakotay's medical data on file and recognize his brain pattern instantly.

On the other hand, there is no telling how the process of his consciousness being detached from his own brain and wandering into another's could alter the energy signature of Chakotay's brainwaves. See more »


[the Doctor gives an overview on how he reintegrated Chakotay's consciousness]
The Doctor: Needless to say, it was a remarkable procedure. I would consider writing a paper about it if there were a convenient forum in which to publish it.

It's ok.
10 February 2021 | by brianjohnson-20043See all my reviews

Not the best episode in terms of the logic of the story of character decisions and motivations. More than once I felt like the characters were being a bit stupid. But if you get over that, it's a fun mystery storyline to try to figure out as a spectator once the storyline gets going. The concept for the story was good. It just didn't get the care that it deserved. And speaking of when the story gets going, the first scene goes on way too long!!! And it doesn't seem to be relevant to the overall story.
