In the quiet, sepulchral halls of a secluded New England home, a young hospice nurse named Lily arrives to care for Iris Blum, an elderly author of classic ghost stories. Portrayed with a delicate unease by Ruth Wilson, Lily is a woman who believes she is easily frightened, a trait that makes her new environment—a house steeped in the legacy of its owner’s most famous novel, The Lady in the Walls—profoundly unsettling. As Lily tends to the ailing Paula Prentiss, she becomes increasingly drawn into the author’s world, sensing a presence that seems to bleed from the pages of Iris’s fiction into the very fabric of the house. Directed with a patient, atmospheric dread by Oz Perkins, this haunting tale weaves a slow-burning tapestry of fear, where the line between story and spectral truth dissolves. The film, also featuring Bob Balaban and Lucy Boynton, is a chilling meditation on memory and the lingering echoes of the past, promising that some stories are never truly finished, and some pretty things are not meant to be seen.
