The Grandmother (2021) is a chilling Spanish-French psychological horror film directed by Paco Plaza (REC, Verónica). The story follows Susana, a young model living in Paris, who must abruptly put her career on hold and return to Madrid to care for her aging grandmother, Pilar, who has suffered a stroke. While Susana expects to stay for just a few days until she can find a full-time caregiver, her time in the apartment quickly devolves into a dark, claustrophobic nightmare. The film masterfully explores the unsettling anxieties of aging, vulnerability, and shifting family dynamics, blending supernatural dread with realistic tension.
