The young woman, named Emily, takes the job as a caregiver for an elderly woman named Margaret. Margaret lives in a large, Victorian house that is filled with antique furniture, chandeliers, and creepy portraits on the walls. As Emily spends more time in the house, she starts to notice strange things happening - doors opening and closing on their own, weird smells, and cold spots.
Margaret is initially pleasant, but Emily begins to suspect that something is not quite right with her. Margaret insists that Emily follow a strict routine and takes an unhealthy interest in Emily's personal life. She seems to know things about Emily that she shouldn't, and Emily starts to feel like she's being watched.
As Emily tries to unravel the mysteries of the house and its past, she begins to uncover a dark history. She learns that Margaret had a son who died under mysterious circumstances, and that the house has a history of violence and tragedy. Emily starts to fear for her own safety as she realizes that Margaret is not the kindly old woman she first appeared to be.
As Emily delves deeper into the house's secrets, she uncovers a connection to her own past that she never could have imagined. Will she be able to survive the dangers of the house and confront the hidden truths that lie within? Or will she become just another victim of the house's dark history?
