Star Wars: Episode V - The Empire Strikes Back (1980) ending / spoiler
Vader plans to freeze Luke in carbonite and present him to the Emperor. He tests it on Han Solo. It’s successful, and a frozen (and alive) Han is turned over to bounty hunter Boba Fett, who is taking him to Jabba the Hutt on Tatooine, Chewbacca, Leia, and C3P0 are taken to Vader’s ship.Luke arrives in Bespin. Vader confronts Luke and after a fierce battle, Vader corners Luke on a narrow catwalk. While dueling, Vader hacks off Luke’s hand with his light saber. He reveals he is Luke’s father and entreats Luke to surrender to the dark side or die. Stunned, Luke refuses and releasing his grip, falls from the platform. Sliding down vertical ducts and corridors, he plunges through a hatch and lands on an antenna beneath city, the planet’s surface far below. Mistrusting Vader and the Empire, Lando frees Leia and Chewbacca and issues an evacuation order to the city. They rush to the landing platform to rescue Han but are too late. As they flee in the Falcon, Leia ‘hears’ Luke calling to her. Telling Chewbacca she knows where Luke is, he turns the ship around. Luke is barely clinging to the antenna rod. They rescue him, and the ship jumps into hyperspeed and escapes. After delivering Luke, Leia and the droids to a rebel convoy, Lando and Chewbacca head for Tatooine to find Han.
