Luke Skywalker has returned to the swamps of Dagobah to complete his Jedi training. His ally Princess Leia fights to rescue her lover Han Solo from the clutches of Jabba the Hutt.
Little do our heroes know that the GALACTIC EMPIRE rushes to build a new space station even more powerful than the Death Star.
If completed, this weapon will spell certain doom for the small band of rebels struggling to restore freedom to the galaxy…
On Coruscant, a group of civilian laborers in a droid factory goes on strike. The Imperial authorities respond with a violent crackdown; a squad of Stormtroopers, led personally by Darth Vader, breaks into the strikers’ safehouse and executes them all.
Above Tatooine, the Emperor personally oversees the construction of a new weapon: the Super Death Star. It is a space station able to jump into a star system, instigate a runaway chain reaction inside the sun, and escape before the rapidly-expanding star destroys all of the surrounding worlds. The Emperor meets with Boba Fett and pays him to assassinate a high-value target.
On the jungle planet Siseman, Lando finds an audience with Jabba the Hutt, towing Chewie and Leia apparently as his prisoners. Having gained entry into Jabba’s palace, Leia unfreezes Han from carbonite and Chewie releases Jabba’s pet rancor. The palace erupts into frenzy as the rancor rampages around and eats Jabba. Our heroes flee amidst the chaos aboard the Millennium Falcon.
Luke continues his training on Dagobah. He climbs a mountain, and when he gets to the top he finds a green crystal that he uses to power his new lightsaber. He talks to Yoda on the mountaintop, who tells Luke about the Anakin backstory and then dies of old age. Luke reunites with R2 and departs from the planet.
Leia, Han, Lando, and Chewie return to the Rebel flagship. Mon Mothma, the Rebel leader, tells them of the mission to destroy the unfinished Super Death Star in the Tatooine system.
Rebel cruisers enter from hyperspace to flank the flagship, but they are tracked by Boba Fett. Slave I destroys the flagship bridge and kills Mon Mothma. Han, Chewie, and Lando take off in the Falcon and defeat Slave I in a space duel, killing Fett. Leia mourns, but then accepts leadership of the Rebels.
Luke reunites with the fleet. Light-hearted banter between all four heroes ensues, then the first phase of the mission begins. The strike team of Luke, Lando, and 3P0, jumps to occupied Tatooine.
On Tatooine, Luke uses his powers to ward off an angry krayt dragon, thus winning the respect of the Tusken Chieftain. Lando and the Chieftain free a captured Sandcrawler from the Empire. Then Luke senses Vader’s arrival in the system and wanders into the desert, where he surrenders himself to Stormtroopers. Vader meets Luke and takes him to meet the Emperor.
On Tatooine, Lando’s assault on the shield base is stalled by Imperial forces, but a surprise attack by the krayt dragon allows the Rebels to turn the tide against the Imperials.
The Rebel fleet fights against the Imperial fleet. The Emperor orders the Super Death Star to fire on one of the twin suns. Han and Leia realize the Rebel fleet has been entrapped.
The Emperor tempts Luke into fighting Vader. Vader reveals that the Emperor is his father, and tells Luke that his fall to darkness is inevitable. Luke is enraged and mangles Vader.
Lando and the native army overpower the Imperial garrison and destroy the shield generator.
Luke refuses to kill Vader, so the Emperor tortures Luke with lightning. Vader intervenes and kills the Emperor by throwing him down a shaft.
The Falcon and other fighters try to find a centralized main reactor but instead see that there is a decentralized power network. Solo realizes he must instead destroy the SDS’s engines, knowing this will mean he and Chewie will lack the time to flee the exploding star.
Luke escapes on a shuttle with his father’s body and Lando flies from Tatooine with the surviving natives. They and the Rebel Fleet all jump to Coruscant. The Super Death Star and the Millennium Falcon perish in the expanding star.
On Coruscant crowds of civilians take to the streets in jubilation. Leia reveals to Luke that she is pregnant. Luke promises to help her raise the child, build the New Republic, and teach the next generation of Jedi.
The spirits of Obi-Wan, Yoda, and Anakin smile upon Luke.
