After slowly building hype throughout 2018, Jordan Peele decided that December was the month we'd finally get our first looks at 'Us', and what better day to release a horrifying trailer than Christmas day?

We knew something was coming shortly from the 'Get Out' writer/director after he teased both the poster and the trailer's arrival on Twitter, and some first look images were released, but now we have a trailer to add to the collection of nightmare fuel that Jordan Peele has already given us.

Here's the official synopsis:

Set in present day along the iconic Northern California coastline, Us, from Monkeypaw Productions, stars Oscar® winner Lupita Nyong’o as Adelaide Wilson, a woman returning to her beachside childhood home with her husband, Gabe (Black Panther’s Winston Duke), and their two children (Shahadi Wright Joseph, Evan Alex) for an idyllic summer getaway.

Haunted by an unexplainable and unresolved trauma from her past and compounded by a string of eerie coincidences, Adelaide feels her paranoia elevate to high-alert as she grows increasingly certain that something bad is going to befall her family.

After spending a tense beach day with their friends, the Tylers (Emmy winner Elisabeth Moss, Tim Heidecker, Cali Sheldon, Noelle Sheldon), Adelaide and her family return to their vacation home. When darkness falls, the Wilsons discover the silhouette of four figures holding hands as they stand in the driveway. Us pits an endearing American family against a terrifying and uncanny opponent: doppelgängers of themselves.

If you read all that before watching the trailer and still want to, you do so at y0ur own peril.

'Us' arrives in Irish cinemas on March 15th, 2019.
