Just before the events of "Star Wars: Episode IV: A New Hope," young criminal Jyn Erso (Felicity Jones) is freed from Imperial custody by the Rebel Alliance. Soon, Jyn and Rebel intelligence officer Captain Cassian Andor (Diego Luna) find themselves on a dangerous mission to steal the plans for the Empire's new weapon, a planet-destroying space station known as the Death Star. The first live-action stand-alone chapter in the "Star Wars" saga also stars Donnie Yen, Ben Mendelsohn, Mads Mikkelsen, and Forest Whitaker.
