A Borg cube heading for Earth is destroyed in a fierce battle with Starfleet, after Picard has pointed out a weak spot in the enemy vessel. The Borg, however, travel back to the year 2063, altering the present in a way that Earth is entirely Borgified. The Enterprise-E follows the Borg to correct history. In 2063, the Borg have attacked the launch site of warp pioneer Zefram Cochrane. While an away team is helping Cochrane's people with repairs, the surviving Borg are gradually taking over the Enterprise-E, and Data is kidnapped by them. After a furious dispute with Worf and Lily Sloane, Cochrane's assistant, Picard reluctantly orders the ship's self-destruction. Nevertheless, he still tries to free Data. Data, pretending to work with the Borg Queen who has provided him with human sensations, finally manages to kill the Borg before the ship blows up. The warp flight and humanity's first contact with an alien species takes place as written in the history books when a ship lands near Cochrane's camp, and a Vulcan exits from the hatch.
