After Voyager encounters an anomaly it is broken in time, different areas being at different periods in time. The only person who can move between the various areas is Commander Chakotay as the treatment given to him by the doctor following the accident has rendered him immune to the effects. He first realises something is wrong when he mentions the Doctor's mobile emitter but he doesn't know what it is. As he explores the ship he finds that the bridge is in a time before Voyager enters the Delta Quadrant, engineering is when the Kazon took over the ship and astrometrics is several years in the future and manned by Naomi and Icheb who are now adults. Once he has realised how he can move about while others can't he gets the Doctor to make more of the antidote so he can recruit Captain Janeway to help inoculate the ship's living gel packs so he can return to the time just before the accident and prevent it.
This was a pretty good episode which had an interesting premise that enabled us to see long gone characters such as Saskia and the Kazon as well as showing us how Naomi and Icheb have grown up to work together. Of course being an episode involving the past the "reset button" is pressed once again as it has been in quite a few Voyager episodes; leaving Chakotay the only crew member to recall the events in the episode.
