Alien: Rey is a crewmember on a small New Galactic Republic freighter bringing a mysterious shipment from an Outer Rim planet. Turns out it's a creature that literally eats the Force, as well as all living things that are given life by it (including humans.) Rey, unknowingly Force sensitive, is the only one who manages to survive when it breaks free of containment. The movie ends as she jettisons the creature into space, then reviews the ship's logs and realizes the New Galactic Republic knew about this dangerous creature all along.
Blade Runner: Finn hunts rogue droids on Coruscant on behalf of the New Galactic Republic, and discovers that a sizeable number of people are actually droids and don't know it. He spends most of the movie trying to find out why there are so many "droid humans" when he ultimately reveals that most of the New Galactic Republic, including the Prime Minister, are actually droids. The film ends on a plot twist in which it is strongly hinted that Finn himself is a droid.
Gladiator: Guilty of being a droid, Finn is sentenced to the Tattooine combat pits where he encounters Rey, who has been hiding from the New Galactic Republic after she was to be arrested for "losing" the valuable shipment. Together, they team up and learn that Rey has Force powers as they win their freedom via the combat pits. Finn divulges that he is actually a droid, and so is a large majority of the New Galactic Republic. Rey then realizes that only droids would be spared if the Force-eating creature were let loose on Coruscant. Finn then realizes that he was hunting "rogue" droids who were planning to make this information known (to warn the humans). The film ends as they realize the New Galactic Republic is actually the Empire.
