In preparation for the trailer debut this coming Christmas, Universal Pictures has shared with EW the first ever photos from Jordan Peele‘s next genre film, Us, which has been shrouded in secrecy since first announced. Now, first details have been revealed and tease what will be a straight-up horror movie with a monster.

“For my second feature, I wanted to create a monster mythology,” Peele tells the magazine.

“I wanted to do something that was more firmly in the horror genre but still held on to my love of movies that are twisted but fun.”

The story is set in the present day and follows Adelaide and Gabe Wilson (Lupita Nyong’o and Winston Duke) as they take their kids to Adelaide’s old childhood beachside home in Northern California for the summer. After a day at the beach with the Tyler family (which includes Elisabeth Moss and Tim Heidecker), Adelaide — who’s haunted by a lingering trauma from her past — becomes increasingly more paranoid that something bad will happen to her family. As night falls, the Wilsons see four figures holding hands and standing silently at the bottom of their driveway…

Nyong’o adds: “it turns into this relentless nightmare that taps into [Adelaide’s] deepest fears and ours as well — the idea that we might be our own worst enemies.”

Peele and his cast are tight-lipped about the horrors that befall the Wilsons, but Peele does reveal to the magazine one key detail: The monsters in his movie are called the Tethered.

Universal has dated Us for March 15, 2019.
