When Voyager encounters an alien whose space "catapult" can speed them back home, a data-overloaded Seven of Nine causes chaos when she incites a civil war then divides the crew with secret allegations of treachery and insurrection.

While Janeway debates accepting the use of an alien's technology that can cut their trip back to the Alpha Quadrant by years, an earnest Seven of Nine processes accompanying information and convinces Chakotay that the captain is sabotaging the true mission of Voyager. Likewise, she privately informs Janeway of a budding rebellion, mysteriously fanning flames that threaten to tear the ship apart.
