Luke in bespin

INT. CLOUD CITY - CORRIDOR - DAY As Luke and Artoo move carefully down a deserted corridor, they hear a group of people coming down a side hallway. Artoo lets out an excited series of beeps and whistles. Luke glares at the tiny droid, who stops in his tracks with a feeble squeak. Boba Fett enters from a side hallway followed by two guards pushing the floating, encased body of Han Solo. Two stormtroopers, who follow, immediately spot Luke and open fire on him. The youth draws his weapon and blasts the two troopers before they can get off a second shot. The two guards whisk Han into another hallway as Fett lowers his arm and fires a deadly laser at Luke, which explodes to one side and tears up a huge chunk of wall. Luke rushes to a side hallway, but by the time he reaches it, Fett, Han, and the guards are gone. A think metal door blocks the passage. Luke turns to see Leia, Chewie, Threepio, and Lando being herded down a second hallway by several other stormtroopers. Leia turns just in time to see Luke. LEIA Luke! Luke, don't - it's a trap! It's a trap! Before she can finish, she is pulled through a doorway and disappears from sight. Luke races after the group, leaving little Artoo trailing behind. INT. CLOUD CITY - ANTEROOM Luke runs into an anteroom and stops to get his bearings. Leia and the others are nowhere to be seen. Behind Luke, Artoo scoots down the corridor toward the anteroom when suddenly a giant metal door comes slamming down, cutting off Luke's exit. Several more doors clang shut, echoing through the chamber. INT. CLOUD CITY - HALLWAY LEADING TO ANTEROOM Artoo stands with his nose pressed against the giant metal door. He whistles a long sigh of relief and, a little dazed, wanders off in the other direction. INT. CLOUD CITY - CARBON-FREEZING CHAMBER - ANTEROOM Luke cautiously walks forward among hissing pipes and steam. Seeing an opening above him, he stops to look up. As he does, the platform he stands on begins to move.
Luke vs Vader

INT. CLOUD CITY - CARBON-FREEZING CHAMBER Luke rises into the chamber, borne by the platform. The room is deathly quiet. Very little steam escapes the pipes and no one else seems to be in the large room. Warily, Luke walks toward the stairway. Steam begins to build up in the chamber. Looking up through the steam, Luke sees a dark figure standing on a walkway above him. Luke holsters his gun and moves up the stairs to face Vader. He feels confident, eager to engage his enemy. VADER The Force is with you, young Skywalker. But you are not a Jedi yet. Luke ignites his sword in answer. In an instant, Vader's own sword is lit. Luke lunges, but Vader repels the blow. Again Luke attacks, and the swords of the two combatants clash in battle.
Luke and Vader are locked in combat on the platform overlooking the chamber. Their swords clash, the platform sways. Luke aggressively drives Vader back, forcing Vader to use defensive tactics. VADER You have learned much, young one. LUKE You'll find I'm full of surprises. Vader makes two quick moves, hooking Luke's sword out of his hand and sending it flying. Another lightning move at Luke's feet forces the youth to jump back to protect himself. Losing his balance, Luke rolls down the stairs to the circular carbon-freezing platform. There he sprawls on the floor, surprised and shaken. Just in time he looks up to see Vader, like a giant black bird, flying right at him. Luke rolls away as Vader lands. Crouching, Luke keeps his gaze steadily on his enemy. VADER Your destiny lies with me, Skywalker. Obi-Wan knew this to be true. LUKE No! Behind Luke the hydraulic elevator cover has opened noiselessly. All the while, Luke slowly, cautiously moves back, away from the Dark Lord. Suddenly, Vader attacks so forcefully that Luke loses his balance and falls back into the opening. There is a rumble, and in an instant freezing steam rises to obscure Vader's vision. Vader turns aside and deactivates his sword. VADER All to easy. Perhaps you are not as strong as the Emperor thought. Through the steam behind Vader something blurs upward. Liquid metal begins to pour into the pit. Vader turns around - and then looks up. He sees Luke, who has leaped fifteen feet straight up and who now hangs from some hoses on the carbonite outlet. VADER Impressive... most impressive. Luke jumps down to the platform where he is separated from Vader by the steaming carbonite pit. He raises his hand. His sword, which had fallen on another part of the platform, swiftly jumps into his outstretched hand and is instantly ignited. Vader immediately lights his sword as well. VADER Obi-Wan has taught you well. You have controlled your fear... now release your anger. Luke is more cautious, controlling his anger. He begins to retreat as Vader goads him on. As Luke takes a defensive position, he realizes he has been foolhardy. A quick sword exchange and Luke forces Vader back. Another exchange and Vader retreats. Luke presses forward. VADER Only your hatred can destroy me. Breathing hard, Luke jumps in the air, turning a somersault over Vader. He lands on the floor and slashes at Vader as the room continues to fill up with steam. Vader retreats before Luke's skillful sword. Vader blocks the sword, but looses his balance and falls into the outer rim of pipes. The energy Luke has used to stop Vader has brought him to the point of collapse. Luke moves to the edge and looks down, but sees no sign of Vader. He then deactivates his sword, hooks it on his belt, and lowers himself into the pit.

INT. CLOUD CITY - TUNNEL AND REACTOR CONTROL ROOM Moving through a tunnellike entrance, Luke cautiously approaches the reactor room. He ignites his sword and moves into the room and toward a large window as Vader enters. Luke raises his sword and moves forward to attack. Behind Luke a large piece of machinery detaches itself from the wall and comes smashing forward toward his back. Luke turns and cuts it in half just as another machine comes hurtling at him. Using the Force, Luke manages to deflect it and send it flying as if it had hit an invisible shield. A large pipe detaches and comes flying at Luke. He deflects it. Sparking wires pull out of the wall and begin to whip at the youth. Small tools and equipment come flying at him. Bombardment from all sides, Luke does his best to deflect everything, but soon he is bloodied and bruised. Finally, one machine glances off his and goes flying out the large window. A fierce wind blows into the room, unmoving, stands the dark, rocklike figure of Vader. A piece of machinery hits Luke and he is knocked out of the window. INT. GANTRY - OUTSIDE CONTROL ROOM - REACTOR SHAFT Luke falls onto the gantry, rolls, and hangs over the edge, holding his deactivated sword in hand. He puts the sword on his belt and begins to scramble up.
final revelation !

INT. GANTRY - OUTSIDE CONTROL ROOM - REACTOR SHAFT Luke moves along the railing and up to the control room. Vader lunges at him and Luke immediately raises his lit sword to meet Vader's. Sparks fly as they duel, Vader gradually forcing Luke backward toward the gantry. VADER You are beaten. It is useless to resist. Don't let yourself be destroyed as Obi-Wan did. Luke answers by rolling sideways and thrusting his sword at Vader so viciously that he nicks Vader on the shoulder. The black armor sparks and smokes and Vader seems to be hurt, but immediately recovers. Luke backs off along the narrow end of the gantry as Vader comes at him, slashing at the young Jedi with his sword. Luke makes a quick move around the instrument complex attached to the end of the gantry. Vader's sword comes slashing down, cutting the complex loose; it begins to fall, then is caught by the rising wind and blown upward. Luke glances at the instrument complex floating away. At that instant, Vader's sword comes down across Luke's right forearm, cutting off his hand and sending his sword flying. In great pain, Luke squeezes his forearm under his left armpit and moves back along the gantry to its extreme end. Vader follows. The wind subsides. Luke holds on. There is nowhere else to go.

VADER There is no escape. Don't make me destroy you. You do not yet realize your importance. You have only begun to discover your power. Join me and I will complete your training. With our combined strength, we can end this destructive conflict and bring order to the galaxy. LUKE I'll never join you! VADER If you only knew the power of the dark side. Obi-Wan never told you what happened to your father. LUKE He told me enough! It was you who killed him. VADER No. I am your father. Shocked, Luke looks at Vader in utter disbelief. LUKE No. No. That's not true! That's impossible! VADER Search your feelings. You know it to be true. LUKE No! No! No! VADER Luke. You can destroy the Emperor. He has foreseen this. It is your destiny. Join me, and together we can rule the galaxy as father and son. Come with me. It is the only way. Vader puts away his sword and holds his hand out to Luke. A calm comes over Luke, and he makes a decision. In the next instant he steps off the gantry platform into space. The Dark Lord looks over the platform and sees Luke falling far below. The wind begins to blow at Vader's cape and the torrent finally forces him back, away from the edge. The wind soon fades and the wounded Jedi begins to drop fast, unable to grab onto anything to break his fall.
