Watch the Eerie First Trailer for Lenny Abrahamson’s The Little Stranger

Our first look at Oscar-nominated director Lenny Abrahamson’s follow-up to 2015’s Room is here.

This time, Abrahamson is helming horror period piece The Little Stranger, adapted from the novel by Sarah Waters. Domhnall Gleeson stars as a country doctor who begins treating a patient at a deteriorating (and, spoiler: haunted) manor. The eerie trailer teases how the doctor becomes entangled with the Ayres family (Ruth Wilson, Will Poulter and Charlotte Rampling) and their frightening circumstances.

The Little Stranger is in theaters Aug. 31. Check out the trailer, poster and synopsis below.

THE LITTLE STRANGER tells the story of Dr. Faraday, the son of a housemaid, who has built a life of quiet respectability as a country doctor. During the long hot summer of 1948, he is called to a patient at Hundreds Hall, where his mother once worked. The Hall has been home to the Ayres family for more than two centuries. But it is now in decline and its inhabitants – mother, son and daughter – are haunted by something more ominous than a dying way of life. When he takes on his new patient, Faraday has no idea how closely, and how disturbingly, the family’s story is about to become entwined with his own.
