Faced with the growing strength of the Empire and the possible dissolution of the Rebel Alliance, Luke, Leia, and Han set off on their own. After a series of dangerous adventures, they join up with the other Rebel characters we met in the previous movies for a battle royale with the evil Empire. At the climax of the film, Luke must face ultimate evil in an epic lightsaber duel.
Who wins? Well, I do not want to ruin the ending, but let's just say lots of people die. Poor Admiral Piett!
