Star Wars: Episode III - Revenge of the Sith

During a space battle over Coruscant between the Galactic Republic and the Separatist Alliance, Jedi Knights Obi-Wan Kenobi and Anakin Skywalker lead a mission to rescue the kidnapped Supreme Chancellor Palpatine from Separatist commander General Grievous. After infiltrating Grievous' flagship, the Jedi engage Count Dooku in a lightsaber duel, which ends with Anakin killing Dooku at Palpatine's urging. Grievous flees the battle-torn cruiser, which the Jedi crash-land on Coruscant. There, Anakin reunites with his wife, Padmé Amidala, who reveals she is pregnant. Initially excited, Anakin begins to have premonitions of Padmé dying in childbirth.

Palpatine appoints Anakin to join the Jedi Council as his representative, but the Council declines Anakin the rank of Jedi Master and orders him to monitor the Chancellor, diminishing Anakin's faith in the Jedi. Palpatine entices Anakin with knowledge of the dark side of the Force, including the power to prevent death. When Palpatine reveals himself as the Sith Lord Darth Sidious, Anakin reports his treachery to Mace Windu, who subdues Palpatine in an ensuing lightsaber duel. In a desperate attempt to help save Padmé, Anakin intervenes on Palpatine's behalf, allowing him to kill Mace. Anakin pledges himself to Palpatine, who dubs him Darth Vader.

Palpatine issues an order for the clone troopers to kill their Jedi commanders, and dispatches Vader and a legion of clones to kill everyone in the Jedi Temple; however, Obi-Wan (having killed Grievous on Utapau) and Yoda survive. Vader then kills the remaining Separatist leaders hiding on the volcanic planet Mustafar, while Palpatine addresses the Senate and reforms the Republic as the Galactic Empire, declaring himself Emperor. On Coruscant, Obi-Wan and Yoda return to the Jedi Temple to discover Anakin's treachery. Concerned by Obi-Wan's reasoning that Anakin has turned to the dark side, Padmé travels to Mustafar to confront him, while Obi-Wan stows aboard her ship. When Vader discovers Obi-Wan, he accuses Padmé of betrayal and uses the Force to choke her into unconsciousness. Obi-Wan battles and dismembers Vader, who is significantly burned by a volcanic river. Back on Coruscant, Yoda confronts Palpatine, but retreats after their duel reaches a stalemate.

Obi-Wan brings Padmé to the asteroid Polis Massa, where she gives birth to twins Luke and Leia before dying. A funeral is held for Padmé on Naboo; meanwhile, Palpatine salvages Vader and brings him back to Coruscant, where his ruined body is repaired with cybernetic limbs and his respiratory suit. Palpatine informs Vader of Padmé's death, devastating him. As the Sith supervise the construction of the Death Star, Obi-Wan and Yoda determine to hide the twins from the Empire. Senator Bail Organa adopts Leia and takes her to Alderaan, while Obi-Wan delivers Luke to his stepfamily Owen and Beru Lars on Tatooine, where Obi-Wan intends to watch over Luke until the time is right to challenge the Empire.
