The first official teaser trailer for Star Wars: The Last Jedi was released on Friday.

In the trailer, Rey is seen training on an island, Finn appears to still be unconscious and Darth Vader's mask is destroyed.

But it's the trailer's ending that offers the most insight to the film, set to open December 15.
