This film is set on the "first contact" between Earthlings and Vulcans, focusing on the "Borg", the archenemy of the "Star Trek Next Generation" TV series. While the Enterprise was conducting a routine cruise in space, Captain Pickett received a secret message saying that the Borg had joined forces from other star systems and prepared to launch an attack on Earth. Since Captain Pickett had been captured and assimilated by the enemy, Starfleet did not trust him very much, so he did not send him to battle. Picot ignored orders and still participated in the battle. The Enterprise followed the Borg's time whirlpool back to the 21st century to stop the Borg's attempt to change the history of human extraterrestrial development to conquer the earth.
