Star Trek: Voyager 7.8 - The Void/Workforce

The Void Trapped in a desolate region of space by a powerful natural force, Voyager is attacked and looted by other ships fighting for their own survival within the void. Facing death by starvation or annhilation, Janeway realises that, to survive in the arena, she must adopt unusual and potentially suicidal tactics. Workforce Returning to Voyager, Chakotay and Harry Kim find the ship disabled and the Doctor alone. More worrying than the disapperance of the crew is the fact that they all seem to be happily holding down day jobs on a nearby planet, with no recollection of their lives aboard Voyager.
