Nika, struggling with loneliness and lack of self-confidence resulting from her asexuality, decides to move to England in search of a better life. She accepts a position as a nanny at the impressive Heelshire family estate. There, she meets eccentric parents who introduce her doll - Brahms - as their son. Surprised, she receives detailed instructions on how to care for it: the doll can never be alone, she has to cook for it, take care of it, read bedtime stories to it, do not invite anyone, do not lock it in, do not leave it alone and kiss it on the forehead before going to sleep. The couple treats the doll like a living child, remembering their son who died in a fire twenty years ago. Nika is warned that she must strictly follow the rules. After the older couple leaves, the disoriented Nika tries to rest, but disturbing things start happening at home. Her things disappear, and she discovers that someone has cut off a lock of her hair. Behind the walls, she hears strange sounds, reminiscent of a child crying. Trapped in an isolated house, with no signal or means of escape, she feels watched. One evening, in desperation, Nika throws away the doll. Then inexplicable things happen: a tear suddenly appears on the wall where the Heelshire family portrait hangs. Behind the painting, she discovers a hidden passage from which the real Brahms emerges. It turns out that the boy survived the fire, but his disfigured face is hidden behind the doll's mask. Dressed in old clothes, he speaks in a childish, sweet voice, but when Nika tries to escape, his eyes burn with anger and his voice becomes menacing, masculine. Brahms, furious that the girl wants to leave him, confesses that he loves her. Living in hiding for years within the walls of the mansion, he forced his parents to find him a nanny, whom he will love and keep for himself.

'Nanny... how can you leave me... come back here!' - growled aggressively the boy who stank and was hairy because he didn't shave. I jumped into the passage in the wall and ran, but it was Brahms' real room. There was a small bed here and on it lay a fabric doll in my clothes. Brahms slept with her, hugged her, imagining me. He was obsessed. I quickly ran through the other corridor and decided to talk. I was standing in the corridor. 'Brahms! Let's talk' - says the girl and the boy comes out of the shadows. He was tall but stocky, there was a mask on his face. He came up, smelling me.
