It’s tough getting acclimated to new roommates, as seen in the new theatrical trailer for The Sleepwalker.

The film, which premiered at the Sundance Film Festival this past January, follows young couple Kaia (Gitte Witt) and Andrew (Christopher Abbott), whose renovations of Kaia’s isolated family estate are interrupted by Kaia’s troubled sister Christine (Stephanie Ellis) and Christine’s fiance, Ira (Brady Corbet). As Christine and Ira spread their battles in the household, deep-seated issues bubble to the surface. And it all gets worse when Christine starts sleepwalking again.

Take a look at the elevated drama of youth in the haunting trailer.
