The newest teaser for “Rogue One: A Star Wars Story” reveals major plot points for the upcoming film.

The international trailer reveals one of the reasons that Jyn Erso (Felicity Jones) is enlisted for the mission to steal plans for the Death Star: Her father, Galen Erso (Mads Mikkelsen), alerted the Rebellion regarding the heist.

“The message was sent by your father,” says Cassian Andor (Diego Luna).

The international trailer also gives viewers new looks at the Death Troopers, dressed in all black, as opposed to the white-garbed Stormtroopers seen in the Star Wars enterprise. There’s not much disclosed regarding their role in the film, but they’re thought to be a part of the Empire’s military intelligence division, meaning they’ll most likely fight against Jyn.

NBC aired the first full trailer for the film last week during its Olympic coverage. Other teasers have revealed that Jyn has been estranged from her father for at least 15 years, suggesting a significant fallout between the two.

“She is not asking ‘who am I and where do I come from,'” Jones said last month at Star Wars Celebration Europe. “Where she comes from propels Jyn’s story. She has had a full life.”

“Rogue One: A Star Wars Story” opens worldwide on Dec. 16.
