The movie opens with a bunch of
Gallofree transports fleeing a
Rebel Resistance base as a bunch of
Imperial First Order Star Destroyers jump into the system, led by a
Star Dreadnought Siege Dreadnaught.
The
Rebels Resistance members narrowly escape with a rag-tag fleet, and the movie's protagonists split up.
Luke Rey lands on
Dagobah Ahch-To, a very rainy and remote planet not known to wider galactic society, where she asks
Yoda Luke--a curmudgeonly old man living like a hermit in a little hut raising his own food--to train her, but he refuses because he feels
Luke Rey is too reckless and undisciplined and because he doesn't want a repeat of the last time he helped train a powerful preteen Force-user,
Anakin Skywalker Ben Solo, who was eventually seduced to the Dark Side by
Palpatine Snoke.
Luke Rey persists, and though she is ignored at first eventually the wise old Jedi Master relents.
We get a montage of the Jedi Master telling his pupil about the history of his Jedi Order, before it was destroyed. Detouring to a brief RotJ interlude,
Obi-Wan Luke talks about how he couldn't redeem
Anakin Ben, and
Luke Rey says he's wrong:
Back to ESB, the Jedi Master shows his apprentice a hole in the ground with a powerful Dark Side presence, and the apprentice goes into the hole to face
his her fears and insecurities. The movie gets a bit trippy, the apprentice faces great internal conflict, and slowly the face of
Vader Rey's parents is revealed to be...
his her own face!
Meanwhile,
Luke Rey has a vision of
Han and Leia Kylo on the far side of the galaxy, and feels that
he she can save them if only she goes to them. She gets into a big argument with the Jedi Master about the vision and leaves to go meet up with them.
Back on the other side of the galaxy,
Han and Leia Finn and Rose have snuck away from the main
Rebel Resistance fleet in a beaten-up ship to go to the idyllic
Cloud City Canto Bight, a neutral city in the current war known for gambling and fancy rich people stuff. They're searching for a top-class con man and smuggler,
Lando Calrissian Maz Kanata's friend, to help them fix a little hyperspace problem. When they get there, the characters discover it isn't as idyllic as it seems, as beneath the surface the dirty work is done by
Ugnaughts human slaves.
There, they run into
Lando Maz Kanata's friend, are arrested by security forces, and are thrown into a jail cell together, where they have a conversation with
Lando a different slicer for no particular reason who fills the same role; he offers help, they say they don't want it. In ESB Lando betrays them to the Empire first and then gives them access to a hyperdrive-capable ship and helps them escape, in TLJ he gives them access to a hyperdrive-capable ship and helps them escape first and then betrays them to the First Order, overall proving him less trustworthy than
Han Finn originally thought. Oh, and their astromech buddy aids greatly in their escape with some novel tools and attachments.
Smash-cut to RotJ.
Han and Leia Finn and Rose need to lead a small group into the
Endor bunker Dreadnought to disable the device screwing over their fleet. To do so, they use
an Imperial a First Order ship with a corresponding transponder, slip through the shields using some stolen codes--which an Imperial officer notices but lets go--and, surprise!, it's a trap, as they're surrounded by bad guys and captured. They escape thanks to timely intervention from their best buddy
Chewie BB-8, who captures an AT-ST and starts shooting all the bad guys.
Luke Rey, meanwhile, has turned
himself herself over to
Vader Kylo Ren. They have a brief conversation on their way to see
Palpatine Snoke, during which the Jedi claims there is still some good in the Dark Sider while the Dark Sider claims it is too late for him and the Jedi should join him instead (which is incredibly close dialogue-wise to the RotJ version). They walk out of the turbolift into a large throne room holding
Palpatine Snoke on a throne surrounded by red-robed royal guards, with a small window looking out into space off to the side.
Palpatine Snoke taunts
Luke Rey, takes off
his her binders with the Force, and gloats about how
he planted the seeds that caused everything to come to pass, how he will destroy the puny Rebellion, and how he will kill Luke Skywalker, complete with taking
Luke's Rey's lightsaber and sticking it on the right arm of his throne and taunting the "Jedi Knight" about taking it back and striking him down.
Luke Rey ends up helpless and weaponless before
Vader Kylo while
Palpatine Snoke assaults
him her with Force powers, and in a shocking twist the Dark Side apprentice kills his master and the throne room starts disintegrating around them.
Smash-cut back to the start of ESB, where
AT-ATs AT-M6s are attacking the secret Rebel base on
Hoth Crait, a remote white planet with a base built into a mountain, complete with massive front door and secret back entrances. (To their credit, it's not a direct ripoff of the Hoth base visually, it's a ripoff of that
and the ANH Yavin IV base.)
Rebel Resistance soldiers dig trenches in front of the base with cylindrical anti-vehicle blaster cannons dotted along them, and the soldiers jump in, pointing their rifles toward the oncoming walkers as one of them looks at the walkers through macrobinoculars (in what is, again, almost shot-for-shot the opening of the ESB battle).
The walker slowly lumber forward until they get within range to destroy the
shield generator front door while low-flying airspeeders that don't have the weapons to penetrate the walkers' armor fruitlessly distract them until they can come up with a crazy plan to take down the thing that will destroy the
shield generator front door. Though the bad guys destroy their objective, the good guys escape to safety on the Millennium Falcon.
