Its' War. The Borg destroyed a colony and direct to Earth. As the Federation sends its warships toward the Borg, Captain Jean-Luc Picard slors que la Fédération envoie ses vaisseaux à la rencontre des Borg, Captain Jean-Luc Picard informs his senior officers that their ship has been instructed to patrol the Neutral Zone. Their orders are to protect the area from any possible Romulan uprising during a Borg attack. Despite protests from his officers, Picard remains faithful to his orders and the U.S.S. Enterprise NCC 1701-E begins to patrol the area. Later, Picard regretfully tells Riker that it is his own fault they are stuck in the Neutral Zone. Starfleet believes Picard to be too emotionally involved with the Borg because of his previous assimilation to tactically complete a mission against them.
Intercepting messages between the starships, the crew learns that the Federation is losing. Picard, with his Borg experience, knows he can help the fleet. He informs his staff that he will make a decision directly in opposition to Starfleet commands. Captain Picard gives the order to the Enterprise to set a course for Earth and the attacking Borg cube.
New Enterprise NCC-1701-E
Despite serious structural damage to the Borg cube, their strength does not weaken. Even the U.S.S. Defiant, commanded by Worf, does not appear to be able to turn the tides of the battle. Picard, having an inside perspective of the Borg and their vessel, focuses the firepower of the fleet on coordinates he knows to be critical. Just as the main ship is destroyed, a spherical escape pod flies out. The sphere creates a temporal vortex, catching the starship Enterprise in its wake. Immune to the paradoxes created by the time travel, the starship's crew learns that Earth at the present time appears to be inhabited entirely by the Borg. The commanding officers realize that the Borg have gone into the past and assimilated Earth, so they follow them back in time to repair the damage the Borg have done.
On Earth, over three centuries earlier, a somber Lily Sloane accompanies a stumbling, drunk Zefram Cochrane out of a bar after a night of revelry. Then, Lily notices a fast moving light. She hardly has time to ask what the object is, when the Borg vessel attacks. Back aboard the U.S.S. Enterprise, Picard demands that Data tell him the exact date and location the Borg ship is attacking. The location: central Montana. The date: April 4, 2063—the day before First Contact. Realizing that the Borg have come to prevent first contact between alien life forms and humans, the crew knows they must stop the Borg and facilitate this exchange. They destroy the Borg sphere, and Crusher, Picard, Data, Riker, Troi and other U.S.S. Enterprise crew transport down to Earth to survey the damage.
Data and Picard hunt for Cochrane's warp ship, the Phoenix that has to complete the first humanity's warp flight. There they encounter a very angry and confused Lily. Overcome by fear and radiation, she falls to the ground. Dr. Crusher takes Lily to sickbay. Geordi is called to help repair the warp vessel.
The Enterprise's crew
Picard is called to the ship and discovers that the survivors from the Borg sphere have transported onto the ship and are taking over Deck 16. The Borg manipulate the climate of the deck to suit their needs and begin to spread throughout the ship. When the Borg attack sickbay, Crusher, her staff, and Lily escape through a Jeffries tube, thanks to a distraction by the ship's Emergency Medical Hologram. While Crusher leads the group down the passageway, Lily steals away in a different direction.
U.S.S. Enterprise around the Earth
On Earth, Riker finds Troi and Cochrane. Cochrane explains to Riker that his only motivation for inventing warp travel was money. He never expected to save mankind, become a hero, or be instrumental in the founding of a new civilization. He simply wanted to retire in peace. Geordi glorifies Cochrane by explaining that his ship will make first contact with alien life forms. Humanity will be saved if Cochrane launches his ship. Still drunk, Cochrane agrees.
Picard hunts the Borg
Picard's team encounters the Borg, who have begun to assimilate U.S.S. Enterprise crewmembers. Data is captured. Picard cannot save him, so he quickly crawls into a Jeffries tube to escape. Face to face with Picard, Lily steals his phaser and demands an explanation and escape route. Picard agrees. They suddenly run into a Borg-infested area. Quickly escaping in the Holodeck, Picard activates a Dixon Hill program. Following the Holodeck's story, Picard searches for Nicky the Nose and takes his machine gun. Killing the Borg with the gun, Picard retrieves the memory chip that contains all of the information the Borg has received.
The Borg Queen
Aware of Data's desire to become human, the Borg Queen offers him the chance to be entirely covered in human flesh and join the Borg, in an attempt to get the encryption codes from Data so she can obtain total control over the U.S.S. Enterprise. Despite his obsession with fighting the Borg, Picard decides to evacuate the ship. Worf, Picard and Crusher activate the ship's self-destruct sequence. The countdown begins, and the crew leaves in escape pods. Picard surveys his ship and prepares to leave when he hears Data calling him...
Spoiler ! the end of the story is revealed below…
Meanwhile, the earth-bound crew and Cochrane begin takeoff. The captain goes to save Data. Entering Engineering, Picard confronts the Borg Queen, whom he knows from his experience with the Borg. Picard offers himself in exchange for Data, but the android does not comply.
He refuses to leave, and at the queen's command, disarms the self-destruct sequence. He quickly enters the encryption codes, offering full control of the Enterprise to the Borg.
As Cochrane's ship nears warp, Data arms the U.S.S Enterprise's weapons and aims them at the defenseless Phoenix. At the Borg Queen's order, Data fires, but the missiles fail to hit the Phoenix. His deception of the Borg complete, Data smashes a conduit, releasing a gas that floods engineering, killing all organic material. As the Borg are destroyed, Picard climbs to safety and the Borg Queen falls into the deadly gas. With the Borg threat gone, Cochrane safely completes humanity's first warp flight. Celebrating the flight back on Earth that night, Cochrane and the Enterprise crew see an alien ship land nearby. The doors open, and Zefram Cochrane makes Earth's first contact with an alien race—the Vulcans. Picard and his crew beam out, having witnessed this historic event, and the U.S.S Enterprise NCC 1701-E returns to the 24th century.
