Kazon intruders board the U.S.S. Voyager and steal a transporter control module. That collateral enables their leader, Culluh, to persuade rival sects to join together to conquer the Federation ship. Surprisingly, the mastermind behind the Kazon's scheme is an advisor with Cardassian, Maquis and Starfleet tactical experience — none other than Seska, the traitor and former intimate of Chakotay. When Chakotay learns that Seska devised the Kazon plot, he secretly sets out alone — against protocol — to thwart her. The Kazon are one step ahead of him and he's quickly captured and brutally interrogated. With their First Officer in the hands of the enemy, the Voyager crew braces for a dramatic showdown, but Seska has more than one trick up her sleeve.
