Task: Question Generation
Input (English): In this sequel to the previous Star Wars movie, Episode IV: A New Hope, the opening crawl reveals that after the destruction of the Death Star, the Rebels were forced to evacuate their base on the Yavin moon and the dreaded Imperial Fleet of the Galactic Empire has pursued the Rebel Alliance across the galaxy, forcing them to establish a secret base on the remote ice planet Hoth. Dark Lord of the Sith Darth Vader (David Prowse/voice: James Earl Jones) sends robotic probes in search of the base and its commander and hero, Luke Skywalker (Mark Hamill).While Luke is patrolling near the base, he sees what looks like a meteor hitting the ground near his location. Before he can ride his mount to the site, he's knocked unconscious by an indigenous, polar bear-like predator, the wampa. Back at the base, the smuggler-pilot Han Solo (Harrison Ford) announces his intention to leave the Rebels and pay the debt he owes to the gangster Jabba the Hutt, much to the displeasure of Princess Leia (Carrie Fisher). After Han discovers that Luke has not returned from patrol, he delays his departure and leaves the base to search for him on an ostrich-like creature called a tauntaun.Meanwhile, Luke escapes the wampa's lair, using the Force to retrieve his nearby lightsaber and wounding the beast, but is overcome by the cold outside. He sees an apparition of his late mentor, Jedi Master Obi-Wan Kenobi (Alec Guinness), who instructs him to receive training from Jedi Master Yoda (voice: Frank Oz) on the planet Dagobah. Han finds Luke and gives him shelter, using his own tauntaun's carcass to keep Luke warm, until he can build a sturdier shelter. The two are rescued the following morning by a Rebel patrol. Luke is taken to the medical bay to heal from the wounds he received from the wampa. In his recovery room he's met by Leia, Han and Chewbacca (Peter Mayhew). Han jovially reminds Luke that he's rescued him twice from certain danger.Sometime later, when ground scans detect an object outside the base perimeter at Zone 12, Han and Chewie, investigate, and find an Imperial probe droid that transmits the location of the Rebel base to the Imperial fleet before firing upon Chewie and destroying itself. On the bridge of Darth Vader's massive flagship, the droid's transmission is picked up by Captain Piett, but his superior, the fleet Admiral Ozzel, dismisses the message until Vader sees the transmission and realizes it is the Rebel base. He overrules Ozzel and orders the Imperial Fleet to the Hoth system.Later, as the Fleet emerges from hyperspace, Vader is informed by his infantry commander, General Veers, that the Rebels have set up infantry trenches and an energy shield to protect them from the Empire's orbital bombardment. Ordering Veers to launch a surface attack, Vader is furious that Ozzel has clumsily given away the element of surprise by bringing his ship out of light speed too close to the planet, and he communicates this displeasure to Captain Piett as he promotes him on the spot to admiral while Ozzel is given Vader's own fatal brand of reprimand.On the surface, the Imperial forces land their ground assault troops, a unit of over a dozen four-legged AT-AT "walkers" (along with a few dozen two-legged AT-ST walkers) beyond the energy shield and Luke leads his squadron of flying speeders into battle. Realizing that their blasters cannot damage the heavily armored walkers, Luke devises an attack plan that has his squad using their towing cables to bind the legs of the walkers to trip them, making them more vulnerable. A few walkers are destroyed but the Imperial forces eventually overpower the Rebels and destroy the generator powering the energy shield, capturing the Rebel base. Han Solo, Princess Leia, Chewbacca, and their droid C-3PO (Anthony Daniels) flee on board the Millennium Falcon. Luke makes it back to the base after personally destroying one of the walkers and speeds off in his X-Wing fighter with astromech droid R2-D2 (Kenny Baker).In space, Han discovers that the Falcon's hyperdrive is damaged and it cannot escape the Imperial blockade in space. During the confusion, they enter the nearby Hoth asteroid field, pursued by four Imperial TIE-Fighters; Han Solo pilots the Millennium Falcon deeper into the field, and the four pursuing fighters are destroyed by the flying rocks. Han lands the Falcon inside a crater on one of the larger asteroids to hide and make repairs.Meanwhile, Luke and R2D2 make a crash landing on the swamp planet of Dagobah. Luke meets a wizened, green little creature who acts obnoxiously, demanding to keep a small power lamp of Luke's and criticizes the rations Luke eats. Telling Luke that he knows where to find Yoda, Luke goes to his small house to eat. While there, Luke quickly grows impatient, wanting to meet Yoda immediately. The small creature begins to talk to the spirit of Obi-Wan, saying that Luke is too old to begin Jedi training and that he hasn't learned the patience a Jedi requires. Luke realizes that the creature is Yoda himself. Yoda insists that Luke harbors much anger like his father, Anakin. Obi-Wan assures Yoda that Luke will learn patience and will complete his training. Luke tells Yoda that he is not afraid, to which Yoda gravely replies, "You will be."The Star Destroyer 'Avenger' moves through the massive asteroid field, searching for the Millennium Falcon. A group of TIE Bombers moves across the massive asteroid where the Falcon is hiding, and they release high-yield concussion bombs on the surface, trying to scare out the Falcon. The noise awakens Leia, who has fallen asleep in the cockpit.Inside the asteroid cave, Han Solo and Princess Leia argue while repairing the ship, eventually leading to a tender kiss. At the same time, Vader orders the Star Destroyer 'Avenger' to search the asteroid field for the Falcon, despite it's captain's assumptions that the ship was destroyed. Vader later confers with his boss, the powerful Galactic Emperor Palpatine, about a new threat to the Empire - Luke Skywalker. Darth Vader suggests that if Luke could be turned, he would become a great ally to the Imperial cause. The Emperor asks, 'Can it be done?'; Vader simply replies, 'He will join us, or die, my Master'.The crew of the Falcon, after getting rid of some annoying mynocks, discover a frightening truth; what they thought was a cave is actually the esophagus of a gigantic space slug. In space once again, they are chased by a Star Destroyer, but Han evades pursuit cleverly and stealthily: after soaring into an attack position, he flies directly over the bridge of the star destroyer and hides the Falcon on the massive ship's surface, attaching to it with the Falcon's landing claws. They go undetected while Han figures out an escape plan. He surmises that the fleet will dump their refuse before jumping to hyperspace and they can float away unnoticed. Han checks his navigational log and realizes he's been in the area before and that a planet called Bespin is nearby.On the bridge of the Avenger, Darth Vader gathers a small group of intergalactic bounty hunters, the most feared of whom is Boba Fett (Jeremy Bulloch). Vader promises them a large payoff if they can find the Millennium Falcon.Han's escape plan works and he sets course for Cloud City, a gas mining colony on the nearby gas planet of Bespin, which is run by Han's friend, Lando Calrissian (Billy Dee Williams). Following just behind him is a smaller ship, Slave I, piloted by Fett.On Dagobah, Luke undergoes Yoda's rigorous lessons about the metaphysical nature of the Force involving levitating objects, performing acrobatic feats and meditation to promote calm and see possible visions of the future. Yoda brings Luke to an old, gnarled tree that sits atop a cave. Yoda tells his apprentice that the cave is powerful with the dark side of the Force and that Luke must explore it. Somewhat distrusting of his master, Luke takes his lightsaber with him. Inside the cave, Luke encounters a vision of Darth Vader, which he fights. Luke cuts off Vader's head with his lightsaber, but then the mask bursts open, revealing Luke's own face behind it. The cave is another test, one that carries a warning for Luke to control his impulses and anger or he'll end up like Vader himself.Luke has a vision of Han and Leia in danger and agony. Luke wants to rescue them, but Yoda and the ghost of Obi-Wan warn of the dangers of rashly leaving, because Luke is still susceptible to the powerful temptation of the Dark Side. Nevertheless, Luke departs from Dagobah and promises Yoda he will return to complete his training.Upon their arrival at Cloud City, Han's party is welcomed by Lando Calrissian. After agreeing to help Han repair his ship, Lando invites him and the others to a meal. C3PO is distracted from the group when he hears the familiar beeping of an R2 unit. Entering a small room, he is suddenly confronted by an unseen person why he's in the room. A laser blast cuts C3PO down as he babbles to his attackers. Only Chewbacca is suspicious, but he arrives on the scene too late to see what happened.When Han's party enter the dining room, they are captured by Darth Vader, along with Boba Fett who had tracked them to Cloud City. Lando insists he was forced to conspire with the Empire to prevent them from invading and occupying the city.In captivity, Han is tortured to lure Luke to the city. Chewbacca is also tortured in his holding cell by an amplified screeching sound. Vader orders a carbon-freezing chamber prepared to freeze Luke, which will hold him in suspended animation for transport to the Emperor. The process is tested on Han Solo. As Han is lowered into the machine, Leia declares her love for him. He is frozen in carbonite and alive in hibernation and handed over to Fett , who intends to return his quarry to Jabba the Hutt for a large reward.Meanwhile, Luke lands at Cloud City and is lured into the carbon-freezing chamber. Luke meets Vader and a ferocious lightsaber fight ensues. While escorting their prisoners, Vader's Imperial troopers are captured by Lando's private security force, who set Lando and the others free. Lando, despite nearly being killed by a furious Chewbacca, insists that there is still a chance to save Han, and along the way they find R2-D2. The group pursues Boba Fett and Han's frozen form through Cloud City, but arrives just as the bounty hunter's ship flies away. After a desperate chase from Imperial troops, Leia, Chewbacca, Lando, and the two droids make their escape on the Millennium Falcon.As the Falcon leaves Cloud City, Luke is trapped on the bottom level of the carbon-freezing room. As he heads down a dark hallway Vader ambushes him, stepping out of a doorway and swinging his lightsaber down. Vader and Luke's fierce lightsaber duel brings them to a narrow platform above the city's central air shaft. The Dark Lord corners Luke on a catwalk, threatening him; 'You are beaten! It is useless to resist!' Luke resumes the fight; Vader suddenly cuts an instrument panel apart. As Luke unwittingly glances at it, Vader slashes off Luke's right hand at the wrist, disabling him and sending Luke's lightsaber tumbling into the huge shaft. With Luke cornered and defenseless, Vader informs Luke that he does not yet know the truth about his father. Luke claims that Vader killed him. Vader answers:"No, I am your father."Luke screams in denial. Vader tries to persuade Luke to join him, embrace the Dark Side of the Force, and overthrow the Emperor with him. Luke refuses, lets go, and falls off the platform into the abyss, signifying that he would rather die than join him. In free fall, Luke is sucked into an air vent, shoots out of the underbelly of the floating city, and lands on an antenna hanging beneath. Luke tries to pull himself back into the exhaust pipe, but with only one hand and no strength left, he is unable to pull himself up and the hatches close over his head, trapping him on the weather vane. He pleads for help from Ben, but the old Jedi Knight will not appear. Luke then attempts to reach out to Leia, using the Force.On the Millennium Falcon Leia senses Luke's distress through the Force and orders Lando to pilot them back to Cloud City -- Lando protests immediately but Chewbacca's roar convinces him to do so. As they approach the bottom of the city, Lando spots Luke hanging on to the weather vane and opens the Falcon's outer hatch. Luke falls off the weather vane and Lando pulls him in just as the three TIE fighters from the 'Executor' appear, and start a rapid pursuit. As they leave Cloud City, they are pursued by Darth Vader's flagship. R2-D2, who discovered that the hyperdrive was merely deactivated while searching the city's central computer, reactivates it and the Falcon escapes into hyperspace. Aboard the flagship, Vader walks away silently.In the final scene, the fugitive and defeated rebel fleet has assembled in a point beyond the galaxy to decide their next move. Aboard a Rebel medical frigate, Luke is fitted with an artificial hand as Lando and Chewbacca set out in the Falcon to locate Han Solo. Luke and Leia watch the ship speed off toward the galaxy.
