Star Wars: A New Hope 1

The galaxy is in a state of civil war. Spies for the Rebel Alliance have stolen plans to the Galactic Empire's Death Star: a space station capable of annihilating a planet. Rebel leader Princess Leia is in possession of the plans, but her ship is captured by Imperial forces under the command of Darth Vader. Before she is captured, Leia hides the plans in a droid named R2-D2, along with a holographic recording. The small droid escapes to the surface of the desert planet Tatooine with fellow droid C-3PO. The two droids are quickly captured by Jawa traders, who sell the pair to moisture farmer Owen Lars and his nephew, Luke Skywalker. While Luke is cleaning R2-D2, he accidentally triggers part of Leia's holographic message, in which she requests help from Obi-Wan Kenobi. The only "Kenobi" Luke knows of is an old hermit named Ben Kenobi who lives in the nearby hills; Owen, however, dismisses any connection, suggesting that Obi-Wan is dead.

During dinner, R2-D2 escapes to seek Obi-Wan. Luke and C-3PO go out after him and are met by Ben Kenobi, who reveals himself to be Obi-Wan and takes Luke and the droids back to his hut. He tells Luke of his days as a Jedi Knight and explains to Luke about a mysterious energy field called the Force. He also tells Luke about his association with Luke's father, also a Jedi, whom he claims to have been betrayed and murdered by Darth Vader, Obi-Wan's former pupil who turned to evil. Obi-Wan then views Leia's message, in which she begs him to take R2-D2 and the Death Star plans to her home planet of Alderaan, where her father will be able to retrieve and analyze them. Obi-Wan asks Luke to accompany him to Alderaan and to learn the ways of the Force. After initially refusing, Luke discovers that his home has been destroyed and his aunt and uncle killed by Imperial stormtroopers in search of the droids. Luke agrees to go with Obi-Wan to Alderaan, and the two hire smuggler Han Solo and his Wookiee co-pilot Chewbacca to transport them on their ship, the Millennium Falcon.

Meanwhile, Leia has been imprisoned on the Death Star and has resisted giving the location of the secret Rebel base. Grand Moff Tarkin, the Death Star's commanding officer and Vader's superior, tries to coax information out of her by threatening to destroy Alderaan and proceeds to do so even after she appears to cooperate as a means of demonstrating the power of the Empire's new weapon. When the Falcon arrives at Alderaan's coordinates, they find themselves in a field of rubble. They follow a TIE fighter towards the Death Star and are captured by the station's tractor beam and brought into its hangar bay. The group takes refuge in a command room on the station while Obi-Wan goes off by himself to disable the tractor beam. While they are waiting, they discover that Princess Leia is onboard and is scheduled to be executed. Han, Luke, and Chewbacca stage a rescue and free the princess. Making their way back to the Millennium Falcon, their path is cleared by the spectacle of a lightsaber duel between Obi-Wan and Darth Vader. Obi-Wan allows himself to be struck down as the others race onto the ship and escape.

The Falcon journeys to the Rebel base at Yavin IV where the Death Star plans are analyzed by the Rebels and a potential weakness is found. The weakness will require the use of one-man fighters to slip past the Death Star's formidable defenses and attack a vulnerable exhaust port. Luke joins the assault team while Han collects his reward for the rescue and leaves, despite Luke's request for him to stay. The attack proceeds when the Death Star arrives in the system, with Darth Vader having placed a homing device on the Falcon. The Rebel fighters suffer heavy losses and, after several failed attack runs, Luke remains as one of the few surviving pilots. Darth Vader appears with his own group of fighters and begins attacking the Rebel ships. Luke begins his attack run with Vader in pursuit as the Death Star approaches firing range of Yavin IV. As Vader is about to fire at Luke's ship, Han arrives in the Millennium Falcon and attacks Vader and his wingmen, sending Vader's ship careening off into space. Guided by Obi-Wan's voice telling him to use the Force, Luke fires a successful shot which destroys the Death Star seconds before it fires on the Rebel base. Later, at a grand ceremony, Princess Leia awards medals to Luke and Han for their heroism in the battle.
