This is yet another big week for Rogue One: A Star Wars Story and fans of the franchise. Throughout the last couple of days, we've been rewarded with cool bits of new footage as everyone anticipates the big full-length trailer launch this Thursday, which is dropping on NBC during their Olympics coverage. Today, Lucasfilm has provided us with the official synopsis, which confirms a plot that centers around a group of rebels trying to steal plans for the dreaded Death Star and stop its galaxy-wide destruction. Here's the synopsis thanks to Disney-centric site Stitch Kingdom.

"From Lucasfilm comes the first of the Star Wars standalone films, Rogue One: A Star Wars Story, an all-new epic adventure. In a time of conflict, a group of unlikely heroes band together on a mission to steal the plans to the Death Star, the Empire's ultimate weapon of destruction. This key event in the Star Wars timeline brings together ordinary people who choose to do extraordinary things, and in doing so, become part of something greater than themselves."

Rogue One: A Star Wars Story is directed by Gareth Edwards. The ensemble stars Felicity Jones, Diego Luna, Ben Mendelsohn, Donnie Yen, Mads Mikkelsen, Alan Tudyk, Riz Ahmed, with Jiang Wen and Forest Whitaker. Kathleen Kennedy, Allison Shearmur and Simon Emanuel are producing, with John Knoll and Jason McGatlin serving as executive producers. Rogue One: A Star Wars Story opens in U.S. theaters on December 16, 2016.

This announcement arrives shortly after new footage debuted yesterday in the way of a 15-second teaser trailer. It showed us some quick scenes featuring new characters such as Jyn Erso (Felicity Jones), Chirrut Imwe (Donnie Yen), Baze Malbus (Wen Jiang) and Captain Cassian Andor (Diego Luna). Also along for this zippy ride was a look at the new U-Wing ship and droid K-2SO, played by Alan Tudyk, who is Cassian's best friend and assistant.

The brand new Rogue One trailer will debut on NBC during the Olympics coverage at some point during the day, but an exact time has not been revealed by Disney and Lucasfilm. We'll be sure to have the trailer for you here as soon as it premieres online. While we're not sure if this is the same trailer that was shown at Star Wars Celebration, it does promise to give us a first look at Darth Vader's return, and there will be a few more surprises as well. So stay tuned.
