Star Trek - First Contact

In their second big screen adventure, the year is 2373 and the crew of the Enterprise-E has learned the Borg has returned. Because of Captain Picard's past experiences with the Borg, Starfleet has ordered the Enterprise to stay out of the fight. Realizing too much is at stake, Picard disobeys orders and takes the Enterprise to Earth. His knowledge of Borg technology leads the Federation fleet to victory, but a Borg sphere escapes and opens a temporal vortex. The Enterprise pursues and travels back to April 4, 2063; the day before the first warp flight.
