The newest trailer for Rogue One: A Star Wars Story dropped Thursday night (August 11) during NBC’s Olympics coverage, and as promised, director Gareth Edwards has delivered a darker, more immersive, more realistic look at that galaxy far, far away — set to the harrowing sound of the Imperial March. Check out the thrilling new trailer below.

At the start of the film, spiritual planet Jedha is seized by the Galactic Empire, which only further fuels the conflict between the Empire and the Resistance. (“Imperial flags reign across the galaxy,” says Forest Whitaker’s grizzled Rebel fighter Saw Gerrera in the opening scene of the trailer.)

Jedha, a desert planet that often attracts spiritual pilgrimages, is known as the Mecca of the Star Wars universe, a place where people still believe in the Force. (Remember: Jedi are thought to be extinct at the time of Rogue One.) There’s also a popular theory that Jedha is a place to harvest kyber crystals, which are used to make lightsabers — and the megalaser for the proposed Imperial weapon, the Death Star.

Meanwhile, protagonist Jyn Erso (Felicity Jones) is a rebel without a cause (with a gun holster inspired by Han Solo), and that’s exactly the kind of attitude the struggling Rebellion needs. As seen in the trailer, she’s tasked with a mission from Mon Mothma: stealing the Galactic Empire’s plans for their shiny new weapon of mass destruction known as the Death Star. Sounds easy enough, doesn’t it?

Of course, Jyn won’t be alone in her endeavor. She’ll be joined by a group of resistance fighters, all of whom make their debut in trailer. Captain Cassian Andor (Diego Luna), her right-hand man, works intelligence for the Rebellion. His best friend is a curmudgeonly Imperial droid that he’s reprogrammed named K-2SO (voiced by Alan Tudyk). Unlike the famed Star Wars droids who have come before him, K-2SO is not an overly emotional guy, as evidenced by his less-than-warm introduction to Jyn. (He’s already our new favorite droid — sorry, BB-8.)

Riz Ahmed plays a former Imperial pilot named Bodhi, seen briefly in the trailer, while good friends Chirrut (Donnie Yen) — a blind warrior-monk who believes in the Force — and mercenary Baze (Jiang Wen) round out the team. It’s their job to steal the Death Star plans from the Empire, which puts them in direct opposition of Ben Mendelsohn’s Imperial Military Director Orson Krennic and his army of Death Troopers. He’s the guy in charge of making sure the Death Star gets completed on time. Or else he’ll face the wrath of everyone’s favorite Sith Lord, Darth Vader, who makes a blink-and-you’ll-miss-it appearance at the very end of the trailer.

Is it just us or does his helmet look too big for his tiny head? Anakin, wyd?
