Captain Jean Luc Picard awakens from a nightmare where he is reliving his assimilation by the cybernetic Borg six years earlier. He is contacted by Admiral Hayes, who informs him of a new Borg attack against Earth. Picard’s orders are for his ship, the USS Enterprise-E, to patrol the Neutral Zone in case of Romulan aggression; Starfleet worries that Picard is too emotionally involved with the Borg because of his past experiences. Learning the fleet is losing the battle, the Enterprise crew disobeys orders and heads for Earth, where a single Borg Cube ship holds its own against a group of Starfleet vessels. The Enterprise saves the crew of the USS Defiant, including Worf, and Picard directs the surviving ships to concentrate their firepower on a single seemingly unimportant point on the Cube. The Cube is destroyed but launches a smaller sphere ship at the last moment. The Enterprise pursues the sphere which approaches Earth and projects a portal, which it enters. As the sphere disappears, the Enterprise discovers Earth has been alteredâ€”it is now populated entirely by Borg. Realizing the Borg have gone back in time and changed the past, the Enterprise follows the sphere through the portal.
As Cochrane, Riker, and Geordi LaForge prepare to activate the warp drive on the Phoenix, Picard discovers that the Borg Queen has been grafting human skin to Data, allowing him to experience the sensation of touch in order to obtain the android’s encryption codes to the Enterprise computer. While Picard offers himself to the Borg in exchange for Data’s freedom, Data refuses to leave. He deactivates the self-destruct and on the Queen’s orders fires on the Phoenix. At the last moment the torpedoes miss, and the Queen realizes Data betrayed her. The android ruptures a coolant tank, and the corrosive vapor eats away the biological components of the Borg. With the Borg threat neutralized, Cochrane completes his warp flight. The next day the crew watches from a distance as an alien Vulcan ship, attracted by the Phoenix warp test, lands on Earth. Cochrane and Sloane greet the aliens. Having ensured the correction of the timeline, the Enterprise crew slips away and return to the 24th century.
