The Girl Before follows Jane, played by Gugu Mbatha-Raw, as she seizes the opportunity to live in a stunning, ultra-minimalist home designed by a mysterious architect named Edward, portrayed by David Oyelowo. The house, a masterpiece of modern design, comes with a strict set of rules that tenants must follow, dictating everything from decor to daily routines. Jane, drawn to the house's sleek aesthetics and the promise of a fresh start, agrees to the terms, unaware of the psychological grip the space will soon have on her.   As Jane settles in, she begins to experience unsettling changes in her behavior and emotions, as if the house itself is shaping her identity. Her curiosity is piqued when she learns about Emma, the previous tenant, who died under mysterious circumstances within the same walls. Digging deeper, Jane uncovers eerie parallels between her life and Emma's, from their past traumas to their interactions with Edward. The more she discovers, the more she suspects that Emma's fate might not have been an accident—and that she could be heading down the same dangerous path.   The narrative deftly intertwines Jane's present-day experiences with flashbacks of Emma's time in the house, revealing a chilling pattern of control and manipulation. Jane's growing paranoia and Edward's increasingly intrusive behavior blur the lines between coincidence and design. As the tension mounts, Jane must confront the unsettling truth about the house and its architect before history repeats itself. The story builds to a gripping climax, leaving viewers questioning the true cost of perfection and the lengths one might go to maintain it.
