It all began 28 years ago with SW EP 4: A New Hope. A young man Luke, from Tatooine, buys 2 robots, R2-D2 and C-3PO, which were sent on Tatooine by Princess Leia Organa to seach for Obi-Wan Kenobi and determine him to help her and the Rebels agains the Empire and Darth Vader, who held her hostage on the Death Star, the ultimate WMD. Luke and Obi-Wan rush to save her with the help of Han Solo, a smuggler, and his best friend, Chewbacca. They are too late to save Princess Leia before she tells Darth Vader were the rebel's base is and despite his promis, Lord Vader destroys Alderan, Leia's home planet. The guys rescue Leia but Obi-Wan dies in a fight with Darth Vader, his former apprentice. Later on the Rebels destroy the Death Star and Luke and Han Solo are welcomed as heros.
Before we continue, you must understand what are Jedies. They are people trained to use the Force (an entity formed by all creatures in the universe), the light side of the force actually, to keep the peace in the galaxy. The Jedi wher called Knights, but some of them, where Masters. Such Master was Obi-Wan Kenobi and Yoda. To become a Jedi, one must star his training with a Jedi at a low age, and was called Padawan (apprentice) until the Jedi Council (formed by a few Jedi Masters, about 8 or 10) decided he/she was readi to become Jedi. By the time A New Hope takes place Obi-Wan and Darth Vader were the last Jedies left alive (in the next Episode we meet Yoda).
The Empire Stricks Back, Episode 5, is considered the best of all (I think ROTS is the best). Here The Empire stricks back on the rebels and destroys their bases on planet Hoth. Luke was sent by Obi-Wan (which died in ANH, but appears to Luke) to planet Dagobath to be trained as a Jedi by Yoda, a great Jedi Master (possible the greatest of all). Yoda has big toubles teaching Luke the Jedi arts. Han Solo and Leia, who fell inlove with eachother, run to Bespine to hide from Darth Vader but they are betraied by Han's friend, Lando Calrissian forced by Darth Vader. Luke leaves Dagobath to save his friends in touble, but arrives to late: Han Solo is freezed and a bounty hunter, Boba Fett, brings him to Jabba the Hutt to whom Han Sole had some depts to pay. Luke fights Darth Vader who tells him that he is his father. Luke looses the fight and Darth Vader cuts his right hand, which is later replaced with a mechanical one. Lando Calrissian saves Leia after all and together manage to save Luke from a ceatain death, after Darth Vader cut his hand.
In "The Return of the Jedi" Leia and Lando fail in saving Han Solo from Jabba the Hutt and fall his prisoners. But Luke comes and save them all. Before he becomes a Jedi he must confront his father again. The Emperor planes to draw Luke to the Dark side and masters a plan for that. Luke is told by Obi-Wan the story of Darh Vader, who was once Anakin Skywalker, the best pilot in the universe and his Paddawan. But he was drawn to the dark side, though it was told by a prophecy that he would bring balance to the Force. Just before he dies, Yoda tells Luke that he must kill his father to become a Jedi. He also tells him that Leia is his twin sister. A second Death Star is under construction and is protected by a shield generated by the Endor's moon. Han Solo, Luke, Leia and Chubacca tries to destroy the shield generator before the fleet of the rebels begins the last major assault on the empire forces. Luke surrends to Darth Vader convinced that he still has something good in him and Vader can be brought to the light side. He fight his father before the Emperor. Luke refuses to sucumb to the dark side and cuts his father right arm, only to discover it was a mechanical arm too. Seeing that Luke cannot be turned, the Emperor decides to kill him. Unders Luke's cries Darth Vader kills the Emperor but he suffers fatal wounds and dies. In the end we see Obi-One, Yoda and Anakin Skywalker appearing to Luke. They are all happy.
