LANDO: Attention! This is Lando Calrissian. The Empire has takes control of the city. I advise everyone to leave before more Imperial troops arrive.
Artoo takes off a computer cover and sticks his computer arm into the socket. Suddenly, a short beep turns into a wild scream. Artoo's circuits light up, his head spins wildly, and smoke begins to seep out underneath him. Quickly, Chewie pulls him away.
LANDO: This way.
Lando, Leia, Artoo, and Chewie flee down the corridor. As he scoots along with them, Artoo sends some angry beeps Threepio's way.
THREEPIO: Don't blame me. I'm an interpreter. I'm not supposed to know a power socket from a computer terminal.
CLOUD CITY - CORRIDOR: In a panic, Cloud City residents are trying to get out of the city. Some carry boxes, others packages. They run, then change direction.
Stormtroopers pursue Lando, Leia, and Chewie who are firing back at them. Artoo works on another door to the landing platform while Threepio berates him for his seeming ineptitude.
THREEPIO: What are you talking about? We're not interested in the hyperdrive on the Millennium Falcon. It's fixed! Just open the door, you stupid lump.
Chewie, Leia, and Lando retreat along the corridor.
A triumphant beep from Artoo - and the door snaps open.
THREEPIO (to Artoo): I never doubted you for a second. Wonderful!
Artoo lays a cloud fog, obscuring everything, as the group dashes outside.
LANDING PLATFORM: They race for the Millennium Falcon as a battalion of stormtroopers reaches the main door. Lando and Leia hold off the troops as the droids get on board with Chewie. As Chewie bounds to the ship the Threepio on his back, Threepio hits his head on the top of the ramp.
THREEPIO: Ouch! Oh! Ah! That hurt. Bend down, you thoughtless... Ow!
Chewie starts up the ship. The giant engines begin to whine as Lando and Leia race up the ramp under a hail of laser fire.
LANDO: Leia! Go!
Artoo drags the partially assembled Threepio down the corridor of the Falcon.
THREEPIO: I thought that hairy beast would be the end of me. Of course, I've looked better.
Artoo beeps understandingly.
MILLENNIUM FALCON - COCKPIT: Chewie works the controls as Leia sits in Han's seat and Lando watches over their shoulders. As Chewie pulls back on the throttle, the ship begins to move.
CLOUD CITY - LANDING PLATFORM - DUSK: The Millennium Falcon lifts gracefully into the twilight sky and roars away from the city. Troops fire after it and TIE fighters take off in pursuit.
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 squatting at the gantry's end. Vader approaches. There is nowhere else for Luke 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! He told me you 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.
REACTOR SHAFT: Suddenly Luke is sucked into an exhaust pipe in the side of the shaft. When Vader sees this, he turns and hurries off the platform.
EXHAUST PIPE: Luke tumbles through the exhaust pipe. He slides to the end of the slickly polished pipe and stops as his feet hit a circular grill and knock it open. Luke claws at the surface of the pipe, trying to keep from sliding out into space.
WEATHER VANE: Unable to hang onto the pipe, Luke tumbles out, emerging at the undermost part of Cloud City. Reaching out desperately, he manages to grab onto on electronic weather vane.
LUKE: Ben... Ben, please!
Luke tries to pull himself up on the weather vane but slips back down. He hooks one of his legs around the fragile instruments. All the while, a powerful current of air rushes out at him from the exhaust pipe.
LUKE: Ben. Leia! . . . Hear me! Leia!
MILLENNIUM FALCON: Leia seems to be lost in a fog, her expression troubled. Chewie is busy operating the ship. Lando stands next to the Wookiee, watching a readout on the control panel.
LEIA: Luke... We've got to go back.
Chewie growls in surprise.
LEIA: I know where Luke is.
LANDO: But what about those fighters?
Chewie barks in agreement with Lando.
LEIA: Chewie, just do it.
LANDO: But what about Vader?
Chewie turns on Lando, the newcomer, with an ominous growl.
LANDO: All right, all right, all right.
MILLENNIUM FALCON: The Falcon makes a graceful banking turn back toward Cloud City.
LANDING PLATFORM: Vader enters the landing platform and watches as the speck that is the Falcon disappears. The wind blows at his cape. He turns to two aides who are standing near the entrance to the landing platform.
VADER: Bring my shuttle.
BOTTOM OF CLOUD CITY - WEATHER VANE: Nearly unconscious, Luke hangs upside-down on the weather vane as his body shifts in the wind.
CLOUD CITY: The Falcon dives to the underside of the floating city. Leia tries to remain calm.
LANDO (pointing out the cockpit window): Look, someone's up there.
LEIA: It's Luke. Chewie, slow down. Slow down and we'll get under him. Lando, open the top hatch.
Lando rushes out of the cockpit.
WEATHER VANE: Luke hangs by one arm from the crossbar of the weather vane. He slips from the bar and grabs onto the pole of the vane as the Falcon banks toward him.
