Retired Starfleet officers James T. Kirk, Montgomery Scott and Pavel Chekov are guests of honor aboard the newly christened U.S.S. Enterprise NCC-1701-B. A test run takes an unexpected turn, however, when the starship encounters two vessels trapped inside the Nexus, a mysterious energy ribbon. During a perilous rescue attempt, Kirk is swept out into space.
Seven decades later, Captain Jean-Luc Picard and the crew of Enterprise-D rescue an El Aurian physicist named Soran. Unbeknownst to Picard, Soran harbors a deadly plan that includes the destruction of the Enterprise and millions of lives. Now Picard's only hope for the future rests within the Nexus - and a legendary captain from the past.
