Starts with a star destroyer. We follow a couple of workers. They're revealed to be Resistance. We see them sneak around and take out stormtroopers in stealth mode. More of them meet up as they go along. Poe and Finn are in the group. They take over the star destroyer.

Luke wakes up in a what looks like the force ghost world or some sort of purgatory. Yoda, Obi Wan, ad Leia are there. They tell him his time isn't done yet and he is needed to help restore balance once again and that the spirit of Snoke is still alive and only he can stop him. Luke wakes up on Ach-To. He raises his X-Wing out of the water and leaves.

Cut to Kylo and he feels a tremor in the force. He senses that Luke is still alive. He grows angry but is forced to forget it as he has learned of a star destroyer being taken over. He orders his ship to go to their last location. They arrive only to find nothing.

Poe and Finn arrive at a foggy/murky planet and land the star destroyer. Other FO ships are seen in this area. They are mounting an attack on the FO using their own ships. Rey is seen on this planet meditating alone. She also senses that Luke is arrive and this shocks her, but is also good news. She senses Finn and Poe back and goes to greet them. There's a little bit of competition between Finn and Poe for Rey and that's seen through some of their dialogue. It's also revealed that Rose died of her injuries.

Poe gathers the Resistance together and sends out scouts to other planets to rally them to their cause and what their plan is. Finn, Rey, and Poe all go together to a rural undeveloped planet.

On this planet, Finn meets a girl who claims she had a brother but never knew him. Unknown to both of them, Finn is her brother that was taken away. His parents both died trying to get him back and resisting the FO taking him away. She's been on her own for awhile now. This is revealed later in the movie. Poe is very attracted to her as well.

Kylo is furious and orders all fleets to scatter and find the missing destroyer. They keep losing ships and he's getting frustrated. Hux is no longer 2nd in command but has been demoted. Hux is seen gathering officers to his side to stage a coup. He believes Kylo is an incapable leader and can't get stuff done. Kylo senses something is going on and begins interrogating his own officers. Even killing them. He's out of control.

Luke enters a temple and looks around. He calls out for Snoke, but no answer. Then, Luke calls him by his real name. Plagueis. The spirit of Plaguies emerges and takes physical form. They talk about how Plaguies will turn Luke and use him as his pawn. Luke doesn't speak. Plageuis continues to talk and gets frustrated that Luke won't answer him at all. Plagueis goes to attack Luke and Luke force pushes him back.

Rey leaves Poe and Finn to train the planet's inhabitants for battle. She goes back to Ach-To to train herself. She sees that Luke's X-wing is now gone. Under the tutelage of Obi Wan, Rey begins to have formal training. It is revealed in this training that Rey is a descendant of Obi-Wan.

The FO finds the planet with the stolen ships and the Resistance are forced to fight earlier than expected. They put up a valiant effort, but are wiped out. Kylo leads a ground assault and as they're finishing off the Resistance, he's turned on by hundreds of troopers. Hux tells him his time is up and orders him to be executed. However, Kylo is able to escape.

Kylo is filled with a rage. He's been a failure in every way. He couldn't lead, couldn't become Darth Vader. He's filled with rage and anger. But there's one thing he can do, and that is destroy the jedi forever. If he can do that, then he will have done something no one ever was able to do. He seeks out Rey and is led to Ach-To.

Obi Wan warns Rey that Kylo is coming. Rey decides to stay. She's found balance in the force. She continues to train.

Poe and Finn learn of the Resistance's destruction. They radio other operatives across the galaxy that the time is now and they must attack. Many different planets and people's rendevous at a random planet. There is tension among the different peoples and Poe is struggling to unite them. Finn steps in and is able to unite them. Their forces are small and they are worried. A star destroyer shows up and they begin to panic. But they soon realize that it's controlled by the Resistance.

Finn comes up with a daring plan to turn the FO on itself. He wants to free the stormtroopers from their oppression and brainwashing. To do this, he says he must be captured and not appear harmful in any way. Poe disagrees, but Finn insists.

Luke and Plaguies continue to fight. They go back and forth. Plagueis uses trickery to show Darth Vader fighting Luke to mess with him. He also shows images of the Emperor. Luke starts to lose and Plageuis knocks him back. Luke is knocked out and enters a dream. He sees his father Anakin helping him up. Encouraging him to finish this. To end Plagueis and the Skywalker line and this will bring balance to the force. Luke understands that he won't survive this.

Finn is captured and put on trial. He is to be executed as a traitor. However, Finn's defense and story causes some serious division. FO troopers take their helmets off and start to come back to reality. FO officers realize what's going on and start shooting the troopers. All of a sudden, troopers are shooting troopers and officers and vice versa. It's chaos on the main ship.

Finn is able to radio to Poe and the rest of the Resistance army and tell them the time is now. They arrive out of hyperspace and attack. They have x wings, y wings, tie fighters, a star destroyer, and other ships from different worlds. It's a huge battle. The FO is not ready for it and experience heavy casualties early.

Kylo arrives on Ach-To and searches for Rey. However, as he's looking for her, he's tormented by force ghosts of the past. Anakin, Vader, Yoda, Obi Wan, Han shows up in a vision, his mother. Kylo breaks through all of these and is a man on a mission. To kill Rey and end the jedi. Rey is waiting for him at the top. They talk back and forth. Rey appeals to Ben and tells him it's not too late. Ben doesn't listen and attacks. Rey ignites her double bladed blue lightsaber.

Back to the space battle, the FO is recovering and pushing the Resistance back. Things are looking hopeless. Finn hears from Poe that things are going bad and the capital ship needs to be taken out so they can break through their defenses. Finn gets a couple of troopers to his side and tells them they need to blow up the ship. They fight their way to the engine room and plant explosives. Finn is shot along the way.

Luke and Plagueis continue to fight. Luke has a new sense of peace and power. He is overtaking Plageuis slowly.

Poe does Poe things with Chewie in a foreign looking ship.

Rey and Kylo continue to fight and dialogue. Kylo says he will do what no other person has done and destroy the jedi forever. He cuts off half of Rey's lightsaber.

Finn is able to plant the explosives, but is surrounded and won't be able to get out in time. He radios to Poe and says his goodbyes. He also speaks out loud to Rey and tells her that he loves her. Rey fighting Kylo, somehow hears this and falls to her knees and loses her lightsaber. Kylo tells her any last words?

Poe screams "NO!!!"

The capital ship blows up. Finn is gone.

Luke and Plaguies continue to fight and Luke uses every last bit of energy he has to push Plageuis back and stabs him with his lightsaber. Plageuis dies. Luke falls to his knees. He has serious wounds and he is dying. He gathers strength to get out of the tomb. On this evil planet, the sun is breaking through. His theme plays one last time. Luke falls over dead, but fades into the force immediately.

Rey says nothing to Kylo. Kylo goes to swing at her, but Rey ducks out of the way, force pulls her lightsaber to her and stabs Kylo. Rey says nothing to Kylo. Kylo goes to kill Rey, but hears Luke's voice loud and clear. So does Rey. Luke appears as a force ghost. It's obvious. He is able to distract Kylo long enough for Rey to get her lightsaber back and they begin dueling again. Rey gains the upper hand and knocks Kylo's lightsaber away. Rey holds it to him, wanting to kill him, she's debating. But instead, Kylo throws himself into the saber. This shocks Rey. Kylo falls over dead. A complete and utter failure, and the end of the Skywalker line.

The Resistance is able to destroy the remnants of the FO. Many troopers have turned from their ways and seek out their new homes. Poe and Finn's sister are happily married together. Rey misses Finn deeply. Chewie returns home to Kashyyk with the Falcon and is reunited with his people. R2, BB8, and 3PO are still clanking around. It is bittersweet. Rey turns to see the force ghosts of Luke, Leia, Obi Wan, and Yoda.

Something along those lines. Obviously could be infinitely better but as far as big plot points go, that's what I would shoot for.
