Continuing the mission he began in "Unification," Starfleet Ambassador Spock endeavors to impart the logic of the Vulcan way to a small band of Romulans eager to unite the Romulan Empire and the planet Vulcan. But unbeknownst to them, a Romulan spy has joined the ranks disguised as a Unification sympathizer. Deceived by this traitor, Spock and his students are taken hostage.Fearful that Spock's knowledge of Federation security will fall into enemy hands, Starfleet dispatches its best ship, the "U.S.S. Enterprise"TM 1701-D, and most respected captain, Jean-Luc Picard, to secure the hostages' release. Spock's former shipmate from the original "Starship Enterprise"TM, Ambassador McCoy -- over one hundred forty years old, but still as feisty as ever -- is brought in to consult on the negotiations.Their situation is further complicated when Captain Montgomery Scott confiscates an out-of-service starship and effects his own daring rescue of Spock. Picard must now find a way to preserve the Federation's security and prevent a war while treading a mindfield of danger and deadly Romulan politics that threaten his ship, his crew, and the Federation he serves.
