Beth Anya Taylor-Joy is introduced in 1967 in Paris, where she awakens in a chaotic hotel room, hurriedly taking green pills and dressing for a highly anticipated chess match. Her journey begins with memories of her childhood in Kentucky, marked by a tragic car accident that claimed her mother, Chloe Pirrie, and left her to be raised in an orphanage. As a young girl, Beth is deeply affected by her mother's last words and the mysterious circumstances surrounding her parents' breakup. She is also introduced to the dangerous allure of pills, which she begins hoarding and taking to cope with her feelings and to enhance her chess abilities.
Beth's fascination with chess starts when she encounters Mr. Shaibel, the orphanage's custodian, who teaches her the game. Initially learned by observation, Beth quickly demonstrates a remarkable aptitude for chess, fueled further by her drug-induced visions that help her develop strategies. Despite her initial failures and intense frustration, she earns Shaibel's respect and begins training seriously. Her talent becomes evident when she defeats Mr. Ganz, the local chess club head, and impresses at a state tournament, even while battling withdrawal from her use of tranquilizers.
As she grows older, Beth is adopted by Alma Wheatley and her husband, Marielle Heller, who provide her with a new environment, though they struggle financially. Beth's obsession with chess intensifies, and she enters increasingly competitive tournaments, quickly ascending in rank. She begins to adapt strategies, study grandmasters, and challenge the dominance of Soviet players, all while grappling with her addiction, insecurities, and the desire for acceptance. Beth’s journey through adolescence is marked by her tumultuous relationship with Alma, her ambitions for greatness, and her tumultuous personal life.
Beth’s talent takes her to international competitions, where she quickly gains recognition. She forms bonds and rivalries along the way, particularly with American player Patrick Kennedy and international stars like Jacob Fortune-Lloyd. Her encounters with the Russian grandmaster Vasily Borgov showcase the challenges of facing a master who views her as a serious threat but also respects her unique style of play. Her fights with addiction, self-doubt, and her burgeoning fame are interwoven with her relentless pursuit of excellence.
Throughout her teenage years, Beth’s personal life is a rollercoaster of triumphs and setbacks. She experiences moments of confidence, such as winning tournaments and earning prize money, but also falls into despair and substance abuse, especially after losses or confrontations with her inner demons. She develops a complicated relationship with her adoptive mother, Alma, depicted with both care and conflict, and struggles with feelings of loneliness and fear, especially in high-stakes tournaments.
Her journey takes her across the globe—from Mexico City to Moscow—as she challenges Soviet supremacy in chess. Her strategic success and resilience culminate in the legendary final against Borgov, where she uses her intuition, mental toughness, and clarity of mind to outplay him in a tense, marathon match. The game is symbolic of her overcoming her personal struggles, including her reliance on tranquilizers and alcohol, and marks her triumph as a chess champion. Borgov recognizes her as one of the greatest players, and she finally conquers her fears that have haunted her since childhood.
The story concludes with Beth returning home, acknowledged as the world’s top chess player, and contemplating her future. She contemplates the complexities of her past—her childhood trauma, her battles with addiction, and her ambition—yet finds a sense of peace in her victory. Her journey from a vulnerable orphan to a resilient champion is one of perseverance, self-discovery, and the relentless pursuit of mastery—both over the chessboard and within herself.
