Star Trek: The Next Generation: Crossover

Ambassador Spock continues his mission to unify the Romulan and Vulcan peoples, but is captured by a Romulan spy. Starfleet dispatches its best ship, the "U.S.S. Enterprise" TM 1701-D, and its most respected captain, Jean-Luc Picard, to secure the release of the ambassador. Ambassador McCoy, now over 140 years old, is also sent to assist in the negotiations. But the situation becomes further complicated when another of Spock's former shipmates, Montgomery "Scotty" Scott confiscates an out-of-service starship and effects his own daring rescue of his friend.
