Star Trek: Generations - Plot

Plot

In the year 2293, recently retired Captain James T. Kirk, Montgomery Scott, and Pavel Chekov attend the maiden voyage of the Federation starship USS Enterprise-B. During the voyage, Enterprise is pressed into a rescue mission to save two refugee ships from a strange energy ribbon despite its lack of readiness. Enterprise is able to save some of the refugees before their ships are destroyed and the Enterprise becomes trapped in the ribbon itself. Kirk descends to the lower decks to alter the deflector shields, allowing the Enterprise to escape. The ribbon makes contact with the ship's hull and causes major damage to the section Kirk is in; being exposed to the vacuum of space, he is presumed to be dead.

In 2371, the crew of the USS Enterprise-D receives a distress call from a solar observatory. They find that everyone, except Doctor Tolian Soran, has been killed by Romulans. The android Data, who recently installed a chip that enables emotions, helps engineer Geordi La Forge search the station. The two discover a compound called trilithium in a hidden room. Soran appears, knocks La Forge unconscious, and launches a trilithium solar probe at the nearby star. The probe causes the sun to go supernova, sending a shock wave towards the observatory. Soran and La Forge are transported away by a Klingon Bird of Prey belonging to the treacherous Duras sisters. Data is rescued just before the station is destroyed.

Enterprise Captain Jean Luc Picard learns more about Soran from Enterprise bartender Guinan; Soran and Guinan were among those rescued by the Enterprise-B. Guinan explains that Soran's goal is to return to the "Nexus", the energy ribbon the Enterprise-B encountered. Picard and Data realize that Soran is altering the path of the ribbon by collapsing stars, and determine that Soran will attempt to reenter the Nexus on Veridian III by destroying its star—and, by extension, a heavily-populated planet in the system. On arrival in the Veridian system, the Duras sisters appear and offer to trade La Forge for Picard. Picard is transported to the planet's surface and finds Soran working on a missile, protected by a shield. La Forge is brought back aboard the Enterprise, unaware that his visor is transmitting a signal to the Klingons. When the Duras sisters discover the Enterprise's shield frequency, they attack. Enterprise is able to counterattack and destroy the Bird of Prey, but takes critical damage. Riker orders an evacuation to the saucer section of the ship to separate from the damaged engineering section. The explosion of the engineering section causes the saucer to crash on Veridian III.

Picard finds a hole in Soran's shield, but is too late to stop him from launching the missile. The Veridian sun collapses and Soran and Picard are transported to the Nexus before the shock wave annihilates the planet. Picard asks for help from an "echo" of Guinan in the Nexus; she sends him to meet Kirk, who is also safe in the Nexus. Picard convinces Kirk to return to Picard's present and stop Soran. The two leave the Nexus, arriving on Veridian III minutes before Soran launches the missile. They distract Soran long enough to lock the missile in place, causing it to explode on the launchpad, killing Soran. Kirk is mortally wounded from the encounter; as he dies, Picard assures him that he helped to make a difference. Picard buries Kirk before being shuttled to the wreckage of the Enterprise saucer section, reuniting with his crew, and leaving the planet.
