Amid a galactic civil war, Rebel Alliance spies have stolen plans to the Death Star, a colossal space station built by the Galactic Empire that is capable of destroying entire planets. Princess Leia Organa of Alderaan, secretly a Rebel leader, has obtained the schematics, but her ship is intercepted and boarded by Imperial forces under the command of Darth Vader. Leia is taken prisoner, but the droids R2-D2 and C-3PO escape with the plans, crashing on the nearby planet of Tatooine. Darth Vader learns of this and orders the Imperials to pursue the droids.
