In the opening sequence, we meet Greta Evans, played by Lauren Cohan, as she travels in a classic British taxi. The path to her destination is secluded, enveloped by dense woods. Awakening from a brief slumber, she steps out of the vehicle, taking in the grandeur of a magnificent manor. The taxi driver informs her that he has already carried her belongings inside while she was dozing. He advises her to wait in the parlor before leaving in the taxi.
As Greta enters the house, she contemplates removing her shoes. After placing them by the entrance, she calls out but finds no one. Hearing a rustle from upstairs, she cautiously ascends the staircase, noting an enormous family portrait of the Heelshires that exudes an aristocratic aura. Calling out again in vain, she explores a room filled with vintage toys. She chuckles while inspecting them but is abruptly startled by a figure in the doorway—it's Malcolm, portrayed by Rupert Evans, the weekly grocery boy for the Heelshire family. As they engage in conversation, it's evident that he has taken an immediate liking to Greta, yet she remains courteous and distant. Malcolm informs her that she is the first American nanny they have hired, having recently moved to the UK.
The conversation turns whimsical as Malcolm shares that his grandmother reads tea leaves while his mother reads palms. When asked what he reads, he humorously responds, "with gum," prompting Greta to give him her chewed gum. His subsequent attempts at palm reading fall short, and he nervously hints at her past, leading to an abrupt change in Greta's demeanor. Curious about the Heelshire family, she inquires about them, especially since no one has welcomed her yet.
Malcolm describes the Heelshires as kind and generous but is cut off when Mrs. Heelshire, played by Diana Hardcastle, makes her entrance. She immediately disapproves of Greta, particularly her lack of shoes. Greta rushes to retrieve them, only to discover they are missing. Mrs. Heelshire dismisses it lightly, claiming, "Brahms likes to play." She insists Greta change into different shoes for their introduction to the family.
As they approach the parlor, the soft voice of Mr. Heelshire, played by James Russell, can be heard talking to Brahms. When he stands, Greta realizes that Brahms is merely a life-sized porcelain doll, which she initially finds amusing until she notices the seriousness etched on the Heelshires' faces. Malcolm tries to lighten the mood by greeting Brahms as if he were a human, which wins Mrs. Heelshire's approval.
During her introduction tour, Greta learns how crucial it is to treat Brahms with care. Mrs. Heelshire shows her the peculiarities of their household, including unique food storage practices and household traps for vermin. Mr. Heelshire shares that the attic is off-limits and emphasizes the importance of following specific daily routines for Brahms, expressing hopes that Greta will be more successful than previous nannies.
As she settles in, we're shown a glimpse of Greta's troubled past during a conversation with her friend, Sandy. We learn that Greta left a difficult relationship with someone named Cole, which adds layers to her character and personal stakes. Although uneasy about her strange new job, Greta is determined to make it work.
Following an unsettling night filled with mysterious occurrences, Greta's apprehensions grow when the doll exhibits signs of movement and agency. After some exploration with Malcolm, whom she grows closer to, she comes to terms with the notion that the doll might be more than a simple relic. Not only does Brahms appear to have an almost sentient quality, but there are also echoes of his tragic past involving a fire and a missing girl.
As the plot thickens, the dynamics shift. The Heelshires' absence allows for a chilling environment where all rules are tested. Following eerie incidents and moments of fleeting connection with Malcolm, Greta finds herself trapped in a cycle of care for the doll, now intertwined with her own survival against the haunting presence of Brahms.
With escalating tension, the film explores themes of love, loss, and the fine line between reality and the supernatural. The climactic encounters force Greta to confront both her past and her fight for freedom against the sinister legacy of the Heelshires and the doll. In a desperate bid to save both herself and Malcolm from the perils that lie within the walls of Heelshire Manor, Greta must gather not only her strength but also her wits to face the darkness that lingers in the shadows.
In the end, Greta's journey reveals that familial ties can be both nurturing and toxic, leading her to a gripping showdown that blurs the lines between protector and prisoner. As she finally escapes the clutches of Brahms, viewers are left wondering whether the ominous legacy truly ends or simply lies in wait for another unsuspecting soul.
