Millie Bobby Brown's fairytale turns into a nightmare in 'Damsel' trailer

Millie Bobby Brown enters a charming new world of horses, dresses, and princes, but not all is what it seems.

In the trailer for Netflix's "Damsel," the "Stranger Things" star plays Princess Elodie, who agrees to marry Prince Henry (Nick Robinson) — only for him to throw her into an underground cave where a dragon awaits.

It turns out that the royal family recruited her as a sacrifice, and her fairytale turns into a fight for survival.

"Damsel" is set to premiere on Netflix on March 8.

Millie Bobby Brown is known for her starring role in "Stranger Things," which began production for Season 5 in January. She also stars in "Enola Holmes," which is currently developing its third installment. —JCB, GMA Integrated News
