Kate’s arrival at the estate is followed by a meeting with the primary caretaker, Mrs. Grose (Barbara Marten), and the cute-but-guileful Flora, and she quickly gets to know the grounds – being a bit disturbed by the story of the previous governess, Miss Jessel (Denna Thomsen) and her quick and mysterious departure. The peace is disturbed, however, by the surprise arrival of Flora’s older brother, Miles (Finn Wolfhard), who has been expelled from his private school, and is immediately hostile towards Kate in her authoritative position. The sibling’s presence adds palpable tension to the household, but making things far worse are the haunting visages that begin to plague the protagonist.
