Rey was a scavenger from the planet Jakku who was abandoned by her parents at an early age, becoming a scavenger for Unkar Plutt, all the while waiting for her parents to return. She found and befriended the Resistance droid BB-8, and helped him and former Stormtrooper Finn to get to the Resistance base so BB-8 could bring a map with Luke Skywalker's location. When Rey met Maz in Maz's cantina, Rey touched Luke Skywalker's old lightsaber and had a vision. Maz then gave Rey the lightsaber, but Rey did not want it so Maz gave it to Finn instead. Maz's cantina was then attacked by the First Order.
Rey was captured and taken to Starkiller Base, but Force mind-tricked a stormtrooper, escaping her restraints. She then sneaked around the base before running into Finn, Han Solo and Chewbacca, who had come to save her and lower the shields, which they had already made Captain Phasma do before throwing her into a garbage chute. She installed explosives on the pillars of the thermal oscillator with the rest of the crew, and watched Han Solo confront Kylo Ren when he arrived, only for Han to be stabbed through the stomach with a lightsaber. She escaped with Finn and Chewbacca, and ran into Kylo Ren outside while Chewbacca went to get their ship.
She was Force pushed into a tree, being knocked out, before barely regaining enough conscious to watch Finn get cut down by Ren. He then tried to Force pull Luke's lightsaber towards himself, but as it was flying through the air Rey also Force pulled it, the momentum carrying it past Ren and into her hands, where she dueled with Ren as Starkiller Base (the planet superweapon that was also the First Order's base) collapsed around them, having been destroyed by Poe Dameron and his two squadrons, finally severely hurting him as well as knocking off his lightsaber from his hand before escaping with Chewbacca and Finn's unconscious body, though Ren escaped with General Hux.
After returning to the Resistance base on D'Qar, she went with Chewbacca to find Luke Skywalker on Ahch-To after the map to Skywalker was put together by BB-8 and R2-D2. She found him in the ruins of the First Jedi Temple, offering him his lightsaber. She later convinces Luke to train her in the ways of the Jedi, during which she and Ren share a connection.
Later, she leaves Ahch-To, goes on board the Supremacy and is brought before Supreme Leader Snoke by Ren. She witness Ren kill Snoke and they both fights his guards. After the duel, Ren offers her to rule the galaxy with him but she refuses and escapes the ship. She and Chewbacca help the Resistance battle the First Order and helps them escape by lifting the rocks that is covering their way. She along with Leia senses Luke's death through the Force. She along with the resistance escape in the Millennium Falcon.
Rey is continuing her Jedi training at the Resistance base under the tutelage of Leia. The Resistance announces that the resurrected Darth Sidious has been manipulating events from the Sith world Exegol and has built a massive armada of Xyston-class Star Destroyers, the Final Order. Rey discovers from Luke's old notes that a Sith wayfinder can lead them to Exegol. Rey, Finn, Poe, Chewbacca, C-3PO, and BB-8 leave for Pasaana, where a clue to the wayfinder's location is hidden. Rey locates the clue—a dagger with Sith inscriptions—with the help of Lando Calrissian. Meanwhile, Rey continues communicating with Ren; through this correspondence, Ren learns where Rey is and comes for her.
Rey confronts Ren, inadvertently allowing Chewbacca to be taken aboard a First Order transport. Attempting to save Chewbacca, Rey accidentally destroys the transport with Force lightning, seemingly killing him. Rey is stricken with guilt and reveals to Finn that she has been having visions of herself and Ren sitting on the Sith throne. Rey and the others travel to Kijimi, where programmer Babu Frik extracts the location of the wayfinder, Kef Bir, an ocean moon of Endor, from C-3PO's memory files. Ren and the First Order follow Rey to Kijimi. Rey senses Chewbacca is alive and the group mounts a rescue mission.
Rey retrieves the dagger aboard Ren's Resurgent-class Star Destroyer Steadfast and has visions of her parents being killed with it; Ren informs her that she is Sidious' granddaughter. Sidious had fathered a son who renounced him; he and his wife hid Rey on Jakku, assuming lives as "nobodies" to protect her. Sidious eventually found Rey's parents and had them killed, but never found Rey. Ren also reveals that as the grandchildren of Sith Lords, their connection is actually a dyad in the Force. Ren urges her to join him so they can overthrow Sidious and take the throne of the Sith together, but Rey refuses and escapes aboard the Millennium Falcon with her friends.
Together, they travel to Kef Bir where Rey retrieves the wayfinder on the remains of the second Death Star; upon touching the artifact, she has a vision of herself as a Sith. Having tracked them, Ren destroys the wayfinder and duels Rey. Leia, dying, calls to Ren through the Force; Rey impales him as he is distracted. Also sensing Leia's death, Rey realizes what she did to Ren and regrets impaling him. She uses the Force to heal him and confesses that she did want to join him as Ben Solo before escaping aboard his TIE whisper.
Disturbed by her Sith lineage, Rey exiles herself on Ahch-To. Luke's Force spirit encourages her to face Sidious and gives her Leia's lightsaber and his old T-65B X-wing. Rey departs for Exegol with the wayfinder from Ren's TIE whisper. Meanwhile, Ren resumes his true identity as Ben Solo. Rey transmits her coordinates to the Resistance, allowing them to launch an offensive against the Sith Eternal forces. Rey confronts Sidious, who demands she kill him in anger for his spirit to pass into her, making her "Empress Palpatine". However, Ben arrives and joins Rey.
Sidious absorbs their life energy to restore his full power and incapacitates Ben. He then attacks the Resistance fleet with Force lightning. Weakened, Rey hears the voices of past Jedi, who restore her strength. Sidious attacks her with lightning, but Rey deflects it using Luke and Leia's lightsabers, killing him and herself. Ben sacrifices himself using the remaining of his energy to revive her using the Force; Rey kisses Ben before he vanishes into the Force. Rey then returns to the Resistance base and reunites with her friends, celebrating their victory against Sidious and the Sith Eternal.
Sometime later, Rey visits Luke's abandoned childhood home on Tatooine and buries the Skywalker lightsabers, having built her own in a yellow color. A passerby asks Rey her name; after seeing the Force spirits of Luke and Leia, she responds, "Rey Skywalker".
