If we take EP I-III and take out only what would not be possible because of no CGI or because it would burst the budget:
EP I 1977 Star Wars (The Phantom menace titel added later after the film was so successful) .
Beginning: A scene similar to ANH. A Republic blockade runner chased by a Trade Federation destroyer. Insted of bording the Trade Fed destroyer just wants to make sure that nothing gets through the blockade of Naboo.
In the last seconds before the ship is destroyed Jedi Master Qui Gon and Jedi Knight Kenobi escape in a Jedi fighter.
They land on Naboo and discover that there is a resistance movement againt the Trade Federation blockade/occupation.
There they meet 16 year old Anakin Skywalker (hated the thing that they had to meet Anakin as a kid in TPM) who is allready a spectacular fighter pilot.
Together they search for Queen Amidala to bring her safely to the Galactic senate. Of cource the queen is hiding in the mountains
( budget
)
They find her, break through the blockade and go to Coruscant - the whole pod race thing would not have been possible in 1977 and not really important for the story.
On Coruscant - resembling something like the city in blade runner-
the Galactic senate (after Amidala has confirmed all the horrible rumours the Senate has heared but had no proof) declare the Blockade/occuparion illegal and send a task force to end the blockade.
A battle similar to the death star battle of ANH.
Qui Gon is killed and Obi Wan takes Anakin as his apprentice.
End: A dark figure clad in dark robes smiling at the news that a powerfull Trade Federation blockade fortress had been destroyed by a single pilot. ( Anakin)
EP II Attack of the Clones
Beginning with a scene of Anakins training to become a Jedi. Then we see short flashes of his training and at the same time other Jedi besides Obi wan observing him and talking about dark times for the Republic.
The dark times are there because of Count Dooku. A poweful dictator from the planet Serreno who in the last 20 years has conquered thousands of star systems in the Outer Rim. Additionally he has made alliances with institutions like the trade federation, the techno union and many other powerful corporations.
The blockade/occupation of Naboo - while executed by the Trade Federation- was his doing. With this move he wanted to keep the Republic occupied while he built up his strenght to challange it directly.
The isolationists in the Republic had prevented the Republic to declare war on Dooku - until now. Dooku had become an unprecedented threat to the peace in the galaxy and the Republic was forced to go to war.
Unfortunately the republic soldiers were hopelessly outmatched by the legions of Dookus Clone troopers. (yeah Clone troopers on the evil side
)
(sorry no room for battle droids)
After the scene with Anakins training and the talking the Jedi learn that Dooku is attacking the planet Geonosis - the gate from the Outer Rim to Republic space. There would be a Hoth like battle between the clones and the republic soldiers just like rebels vs empire in TESB.
The Republic is badly beaten in this battle. They know they have no chance against the clones. So all Jedi are sent out to seek and destroy the clone factories.
Anakin makes a stop on Naboo and it is revealed that he has a wife there - someone he met during the resistance - and she is pregnant
End: A military control room with a map of the Galaxy. Count Dooku is seen and he is very satisfied with the progres. A figure in black robes approaches him and Dooku admits that without the figure he would never have come so far. And again it is the same figure seen in Episode I smiling.
EP III
While having destroyed many of the smaller clone factories the attack on the main clone factory has failed. Dooku enraged at the near loss of this precious installation decided to attack Coruscant directly and end the war as soon as possible.
The Republic was loosing, badly. It was only a matter of time until Dookus clones would conquer Coruscant. With this the war would be as good as over. But just when it seemed that the Republic was beaten an enormous unknown fleet appeared out of nowhere and repelled Dookus invasion of Coruscant.
It was a Fleet comanded by the representative of Naboo, Senator Palpatine. The Naboo had begun construction of this secret fleet the day after the liberation from the Trade Federation to ensure that they would never again be enthralled by a foreign power.
The Battle of Coruscant was the turning point of the war.
Due to the interference of the unknow Naboo fleet Dooku had lost more ships and clones in this single confrontation than in the last 20 mayor battles combined.
His empire was crumbling. Realising defeat was inevitable Dooku made preparations for a final stand on Serreno.
It was then that the cloacked figure from EP I and EP II approached Dooku and killed him. Just seconds before Dooku died the cloacked figure revealed its true identitiy and Dooku realised that he had been a puppet his entire adult life.
The cloacked figure was no other than Senator Palpatine. It was not hard for the cloacked fígure to convince Dookus followers that the Jedi had assasinated their leader. After all Dooku had been killed by a lightsaber - that was obvious from the hole in his chest.
While Dooku was dead and his followers would loose the war very soon they would drag the Galaxy with them. A Galaxy in flames.
Just minutes after Dookus death a galaxy wide suicide order for all clones was given out. All clones should execute suicide attacks on anything that was associated with the Republic.
The damage was enourmous. The only way to stop the clones from suicide attacks was to break into the command center on Serreno and give the order to stand down.
But even the combined Republic/Naboo fleets would need days to battle through Dookus defences. So a plan was formulated - while the Republic/Naboo fleets would occupy the rest of Dookus forces all the Jedi left in the Galaxy would attack Serreno with small one or two person fighters.
With luck at least one of the remaining 600 Jedi would get through to the command center and give the stand down order for the clones.
There would be a short battle of Endor like space battle
(short because budget
) and then a group of some 20 or 30 Jedi - all that was left- assaulting a command structure.
Strangely there would be no opposition. But once inside the main control room they would encounter Palpatine with hundreds of clone soldiers.
There Palpatine would reveal that he was a dark Jedi and a user of the dark side of the force and that all this had been his doing.
Anakin - having entered the Jedi training with 16 - would be pissed of and angry as hell and would want to attack Palpatine - the other Jedi would say - dont give in to your anger it leads to the dark side.
Just then would Palpatine show Anakin fake pictures from his pregnant wife beeing killed by clone soldiers. Now Anakin would be mad as hell - one Jedi would try to stop him and in his anger Anakin would chop him to pieces.
Thus Anakin has turned to the drak side and Darth Vader is born.
He blames the Jedi for his wifes death : Because of the stupid Jedi policies he had to keep his wife on Naboo where she was killed.
Anakin immediately battles with Obi wan while the rest of the Jedi try to get through the hundreds of clone troopers to shut down the suicide attack order.
Obi wan defeats Anakin, Anakin is severely injured and will have to wear the Darth Vader body armour to keep him alive.
The rest of the Jedi are slaughtered by the clone troopers and only the two luckiest - Obi Wan Kenobi and Yoda manage to escape.
The last two Jedi in the Galaxy.
Palpatine gives the stand down order for the clones in the Galaxy.
To the galaxy he presents himself as the one who defeated Dooku and saved the galaxy.
He crowns himslef emperor. The galaxy applauded, after all he and his secret Fleet had saved the Republic from its enemies. The plan of the dark Jedi had worked perfectly.
Having learned that Anakin had a wife Yoda and Obi Wan travelled to Naboo where they meet young Padme. While not dead the young woman had been severely injured by a suicide clone attack.
She lives long enough to give birth to Baby Like and Lea but dies afterwards.
After his reconstruction Palpatine tells Vader that his wife is alive and well. Vader immediately travels to Naboo. The only thing he finds there is Padmes grave and the feint remains of Obi Wans and Yodas presence.
Convinced that they were the ones that killed her he was determined to make make them pay.
Obi Wan and Yoda hide and Luke and Lea are split up.
The Next three Star Wars movies wount come out until 1999-2005.
Their titels beeing A New Hope, The Empire Strikes Back, Return of the Jedi..............
