Luke Skywalker(Mark Hamill) stays with his foster aunt(Shelagh Fraser) and uncle(Phil Brown) on a farm on Tatooine. He is desperate to get off this planet and get to the Academy like his friends, but his uncle needs him for the next harvest. Meanwhile, an evil emperor has taken over the galaxy, and has constructed a formidable "Death Star" capable of destroying whole planets. Princess Leia(Carrie Fisher), a leader in the resistance movement, acquires plans of the Death Star, places them in R2-D2(Kenny Baker), a droid, and sends him off to find Obi-Wan Kenobi(Alec Guinness). Before he finds him, R2-D2 ends up on the Skywalkers' farm with his friend C-3PO(Anthony Daniels). R2-D2 then wanders into the desert, and when Luke follows, they eventually come across Obi-Wan. Will Luke, Obi-Wan and the two droids be able to destroy the Death Star, or will the Emperor rule forever?
