About the series
Contains story spoilers.
Beth Harmon’s story begins with a rupture: after her mother dies in a car crash, nine-year-old Beth is sent to the Methuen Home for Girls in Kentucky. The institution’s quiet basement becomes her first refuge. There she watches the custodian, Mr Shaibel, play chess alone, persuades him to teach her, and quickly absorbs the game’s patterns. The orphanage also distributes green tranquilizers to the children; Beth discovers that the pills can turn imagined positions into vivid images on the ceiling. Chess and medication become intertwined tools for managing a world in which she has little control. Later, the same visual habit offers her a private rehearsal space, letting her replay positions without an opponent or a physical board. Its power comes with a cost: she learns to trust a chemical aid instead of asking for help.
When Beth is adopted by Alma and Allston Wheatley, her surroundings change to a tidy suburban home, but her habit of retreating into calculation remains. At school she studies the boys around her, then enters a tournament despite having no formal club experience. She beats experienced opponents, including the older Harry Beltik, and draws attention beyond the local chess scene. The tournament winnings give her a measure of independence and help her and Alma travel to Cincinnati and later Las Vegas. Alma, initially an uncertain guardian, becomes Beth’s companion and business partner on the circuit, arranging travel and engaging with the press while Beth concentrates on the board.
The series follows Beth from local competitions into a national and international chess culture where she is usually the only woman in the room. Her success attracts headlines that frame her as a novelty as well as a formidable player. In Las Vegas she meets Benny Watts, a cocky American champion whose skill and theatrical confidence make him a more challenging opponent than the earlier players she defeated. Their relationship shifts from rivalry to a complicated mentorship. Benny exposes the limits of Beth’s self-taught approach, while she resists being managed or treated as a project. Chess mastery opens doors, but fame and the expectation that she represent women players bring a different kind of pressure.
A trip to Mexico City places Beth’s ambitions beside her mother’s private life. Alma has begun corresponding with a man named Manuel, and Beth sees that her adoptive mother has needs and secrets beyond chaperoning tournaments. There Beth plays the Soviet champion Vasily Borgov and loses, a defeat that unsettles the certainty she had built from rapid victories. When Alma dies during the trip, Beth returns to Kentucky bereaved and alone. Her later drinking and use of pills intensify; the routines that once supported her preparation become unreliable, and she begins missing obligations and losing control away from the board.
Back in Kentucky, Beltik visits and tries to help Beth regain her footing. He studies chess with her, but their partnership cannot give him the equal place in the game that he wants, and he leaves. Jolene, Beth’s childhood friend from Methuen, later reappears with money and a practical offer of support. Their reunion reconnects Beth with the institution she had tried to leave behind. Jolene tells her that Mr Shaibel kept a record of Beth’s tournament career, evidence that the quiet custodian had followed her progress even after she became famous. Beth’s discovery of his scrapbook gives her a clearer sense of the care she had failed to recognize while she was racing toward the next match.
After Beth and Beltik separate, she wins the U.S. Championship in Ohio by defeating Benny Watts. He takes her to New York to prepare for Paris, offering an air bed in his basement apartment and insisting on sober practice. His friends join their sessions, and Beth beats three opponents simultaneously at speed chess. When Cleo offers a drink there, Beth refuses. Paris brings the reversal: Cleo calls the night before the Borgov rematch, and Beth agrees to meet for what she intends to be one drink. She wakes in the bathtub the next morning, takes a tranquilizer and hurries to the match. Hungover and struggling to concentrate, she plays Borgov and resigns. Back home, Benny urges her to return to New York, but she chooses isolation, allowing drinking to fill the hours that previously belonged to preparation.
In the final stretch, Beth accepts Jolene’s help and returns to competitive play in Moscow. The American delegation hopes to use her success as a Cold War symbol, but Beth is wary of being turned into a political instrument. During the adjournment of her final match with Borgov, her former opponents gather by telephone and work through possible lines with her, replacing the isolation she once considered essential with shared preparation. Beth defeats Borgov, who acknowledges her victory, and then asks to leave the car taking her toward the airport, then joins older men playing chess in a public park. The ending brings her back to the game as a human exchange: she can still compete fiercely while choosing connection and pleasure over the need to prove that she belongs.
