Encountering a deadly radioactive nebula, Captain Janeway decides to save time by going through rather than around it and orders the crew into protective stasis chambers with Seven of Nine to take lonely command. With the entire crew now in cryogenic sleep, and only the Doctor for company, Seven of Nine is the only living being walking the ship's hallways. The long and lonely journey through the nebula begins to play tricks on the former Borg's mind as she experiences what humans call "hallucinations." An alien, Trajis Lo-Tarik, also making his way through the nebula, asks to trade some vital supplies, but his presence unleashes a series of events that Seven can't decipher as to whether they are real threats — or even if Trajis himself is real.
