Deanna Troi is unknowingly brought aboard the Romulan Warbird Khazara and has cosmetic surgery to make her look like a Romulan. Subcommander N'Vek privately explains that he has no intention of harming her, but needs her help to pose as Major Rakal of the Tal Shiar, the Romulan intelligence service and secret police. N'Vek has secret cargo to the Federation, and needs Troi to act her role to convince the Khazara commander, Toreth, who is not aware of N'Vek's plan, into complying. Troi, as Rakal, is able to sway Toreth to head for a planned rendezvous in the Kaleb sector under threat of intense interrogation techniques.

Aboard the Enterprise, the crew brings aboard Stefan DeSeve, a human who had served as an ensign in Starfleet before defecting to the Romulans. Now he has returned with a message from Ambassador Spock. Captain Picard, wary of his prisoner's motives, considers Spock's message regarding a meeting in the Kaleb sector that would be prudent for the Federation's interest, and directs the ship there.

As the Khazara is en route, N'Vek shows Troi the secret cargo - a high official and two of his aides, held in stasis. They wish to defect to the Federation, and his presence there would aid further Romulan dissidents to flee the Empire. The plan is to transport the stasis chambers to a Corvallen cargo ship at the rendezvous point, who will subsequently deliver them into Federation space. When the Khazara meets up with the cargo ship, Troi senses its captain is not trustworthy, and N'Vek fires upon it, destroying it. He claims he was ordered by Major Rakal. Troi later explains to Toreth that she recognized the captain of the cargo ship as a known Federation spy. N'Vek, in private, explains to Troi that their only other option is to travel to Draken Four, an entry point for the Federation, where Troi can use her Starfleet codes to allow the ship to enter undetected. Troi gives this order to Toreth, who reluctantly agrees to it. However, their conversation is interrupted by the arrival of the Enterprise.
