Chakotay, Kim and Neelix, return from their trading mission on the Delta Flyer to find the ship abandoned and adrift in a nebula, with only the Doctor on board. The Doctor informs them that the ship fell into a trap which forced them to abandon ship in the escape pods, allowing them to be captured. The Doctor has heard nothing from them since. They find the crew of Voyager living as workers on an industrial planet called Quarra, totally unaware of their time on Voyager or their situation in the Delta Quadrant. After going undercover on the planet, Chakotay, Kim, Neelix and the Doctor must now find a way to return the crew and restore their memories, while evading local authorities who have uncovered their plan.
