The Maid (2009)

Raquel, a long-time live-in maid for an affluent family, finds herself trapped in a monotonous routine that has drained her spirit. Struggling with painkiller dependency, she resorts to juvenile pranks to assert her influence, particularly against the family’s college-aged daughter and the rotating cast of new staff. Her disruptive behavior effectively isolates her, until Lucy, the latest maid, challenges Raquel's authority. This unexpected confrontation forces Raquel to confront her loneliness and the consequences of her actions, leading to a transformative clash between tradition and change within the household.
