Nina Sherl, a 23-year-old Texan, leaves behind her quiet countryside life to start a new chapter in England, having secured a job across the world. Arriving at the airport, she meets Theo Diaz, a tall, handsome man dressed in a sharp suit, who has been sent to pick her up. Their journey together begins with an awkward but kind exchange, including a meal at a classy restaurant where Nina nervously navigates their first interaction.
Upon arriving at the grand mansion, Nina is introduced to her new life-filled with luxury, quiet moments, and new faces. Theo, though distant, explains that she'll be looking after his younger sister, Lidia, and makes her feel at ease as she settles in. As Nina adjusts to her new role and surroundings, she becomes acutely aware that this is only the start of a much larger, more complicated story.
