The trailer starts out with a flashback of Jyn Erso and her father, finally connecting the pieces of how he’s involved with the Death Star construction. Then it moves on to the current mission and the rag-tag group of fighters involved.
Disney released two international posters for the film last month (see “'Rogue One: A Star Wars Story' Posters”). The previous trailer can be seen here: “New 'Rogue One' Trailer.”
The film opens in theaters on December 16.
