The new sneak peek puts the spotlight on Sophie Turner's Jean Grey.

Looks like there's a major death coming to the X-Men, at least judging by the first trailer for the franchise's latest release, "Dark Phoenix."

The film -- a continuation of "First Class," "Days of Future Past" and "Apocalypse" -- is an adaptation of the "Dark Phoenix Saga" from the Marvel comics, which finds Jean Grey (Sophie Turner) turning to the, well, dark side after an almost fatal accident in space.

Much of the footage revolves around Grey, focusing on her traumatic childhood and extreme power.

Here's the official synopsis from Fox:

In Dark Phoenix, a telepathic and telekinetic Jean Grey discovers her true potential after nearly being killed during a rescue mission in space. When she returns, she finds herself limitlessly stronger, but also unbalanced. As she battles with this new reality, Jean unleashes her powers in ways she can't understand or contain. Spiraling out of control, she hurts the people closest to her, while also unraveling the ties that hold the X-Men together. With this family beginning to crumble, they must find a way to unite to save Jean's soul and to prevent aliens from weaponizing on this new power and taking over the galaxy.

This will likely be the final X-Men film for this cast, who will probably be replaced when Disney starts churning out their own movies thanks to their purchase of Fox.

It's definitely, however, over for at least one of them, as Beast (Nicholas Hoult) and Storm (Alexandra Shipp) are seen mourning someone's death at a funeral. Who is it? Based on Beast's tears and not really anything else, our money's on Mystique (Jennifer Lawrence).

"This movie is kind of a lot more emotion-based, much more grounded," Turner told Digital Spy earlier this year. "There are, of course, those supernatural elements, but this one is really character-driven – a really emotional story about a girl battling with a deadly mix of mental health problems and being a superhero."

"I put my heart and soul into that movie," she added. "It was so fun, but it was such a stretch."

James McAvoy and Michael Fassbender will return in their roles as Charles Xavier and Magneto. Other returning stars include Tye Sheridan (Cyclops) and Kodi Smit-McPhee (Nightcrawler), while Jessica Chastain also joins the cast.

After initially being set for a November 2018 release, the movie will hit theaters February 14, 2019.
