The abduction in 2377 of most of Voyager's crew, whose memories were altered so that they would work contentedly in the industrial plants of the labour-starved planet Quarra.
The Quarren abduction of Voyager's crew is told in the two-part Voyager story Workforce. Chakotay, Harry Kim and Neelix come back from a trading trip to find the ship drifting in a nebula with only the Doctor aboard, running as the Emergency Command Hologram. The crew were forced out by a mine and collected in their escape pods.
On Quarra the missing officers have been given false pasts by a doctor named Kadan and jobs at a power plant. Kathryn Janeway believes she came from an overcrowded world and is happy with a colleague, Jaffen. Tuvok begins to remember and passes fragments to Seven of Nine by mind-meld before he is taken away for further treatment.
Chakotay goes among the workers in disguise and is hurt. With the help of a local investigator, Yerid,, the conspiracy is uncovered, and the crew are returned to Voyager and treated.
