In the world of the wealthy Winchesters, the new housemaid finds herself trapped in a web of lies and manipulations. Tasked with the cleanliness of their opulent home, caring for their daughter, and cooking for the family only to dine in solitude, she observes strange behaviors from her employers. Nina Winchester commands attention with cruel games, while her husband grows increasingly tormented. A fleeting fantasy in one of Nina's dresses binds the housemaid to a chilling reality: her attic room's lock is a signal of her captivity, not safety. But the Winchesters are oblivious to the truth of her past and unaware of what she is driven to do. 'The Housemaid' explores the fine line between servitude and control, and how desperation can lead to dark and unexpected places.
