Rogue One: A Star Wars Story is directed by Gareth Edwards, it’s the first of the new standalone features from Lucasfilm and Disney, which take place outside the core “Skywalker Saga” of films noted by an Episode number. Rogue One tells the story of the small band of rebels that were tasked with stealing the plans to the first Death Star. The story spins directly off the opening crawl from the original Star Wars: Episode IV – A New Hope. In that crawl, it read: “Rebel spaceships, striking from a hidden base, have won their first victory against the evil Galactic Empire. During the battle, Rebel spies managed to steal secret plans to the Empire’s ultimate weapon, the DEATH STAR, an armored space station with enough power to destroy an entire planet.”
