Part One
Klara and her fellow Artificial Friend, Rosa, begin their existence inside a store, where they observe the outside world through the front display window.
Klara stands out for her remarkable observational abilities, a trait the Manager frequently praises. She watches office workers, passing taxis, and a Beggar Man with his dog, slowly forming a belief that the Sun provides essential nourishment to all living things.
A girl named Josie visits the store and makes a heartfelt promise to return and purchase Klara.
During her days in the window, Klara witnesses a wide spectrum of human emotion, including a violent altercation between two taxi drivers and a deeply moving reunion between an elderly man and woman.
She also notices that older AF models seem anxious about being replaced by the newer B3 models rolling into the store.
Pollution from a Cootings Machine temporarily blocks the Sun, an event Klara perceives as a direct threat to her own well-being and to everyone outside.
Rosa is eventually purchased by another family, leaving Klara alone and increasingly worried that Josie may never return.
When Josie finally does come back, her mother Chrissie subjects Klara to a rigorous test, asking her to mimic Josie’s unique, slightly impaired walk.
Klara performs the imitation flawlessly, demonstrating an intimate grasp of Josie’s physical vulnerabilities.
Despite the arrival of more advanced AF models, Josie insists with unwavering certainty that she wants only Klara.
The Manager quietly warns Klara that children often make and break promises, but Josie remains steadfast. Chrissie eventually agrees to the purchase, and Klara is taken to her new home, ready to begin her life as Josie’s devoted companion.
Part Two
Life at Josie’s house proves complicated from the start, largely due to the hostility of Melania, the housekeeper, who views Klara with open suspicion. Klara learns that Josie’s illness leaves her weak and frequently unable to attend interaction meetings with other lifted children.
She meets Rick, Josie’s neighbor and childhood friend, who is unlifted and therefore faces a future with far fewer opportunities.
Rick and Josie share a secret plan to spend their lives together, despite the rigid social divide separating lifted and unlifted individuals. During one interaction meeting, Klara observes the casual cruelty of the other lifted children, who suggest tossing her across the room to test her coordination.
Rick intervenes to protect Klara, his moral compass clearly different from that of Josie’s privileged peers.
On a walk with Josie and Rick, Klara spots a barn in a field and identifies it as the Sun’s resting place, a location that will later become central to her spiritual mission.
Chrissie remains a tense and grieving figure throughout, still mourning the death of her older daughter Sal, who perished after undergoing the lifting process. A planned trip to Morgan’s Falls nearly falls apart when Josie becomes too ill to travel, but Chrissie decides to take Klara alone instead.
At the waterfall, Chrissie commands Klara to “be Josie,” forcing the AF to imitate her daughter’s voice, mannerisms, and personality.
This unsettling episode reveals the true, heartbreaking reason Klara was purchased: Chrissie is testing whether Klara can replace Josie if the worst should happen. When Josie discovers that Klara went to the falls without her, she feels hurt and betrayed, and the two grow temporarily distant.

Part Three
Josie’s health continues its alarming decline, confining her to bed for extended stretches and casting a pall over the entire household. Rick visits faithfully, and the two play a bubble game in which they fill in thoughts for the characters Josie sketches.
These drawings quietly expose the children’s hidden anxieties about their futures and the crushing pressures of the society they inhabit.
Rick’s mother Helen approaches Klara with an urgent request: use her influence to persuade Josie to help Rick gain admission to Atlas Brookings, the only college that accepts unlifted students.
Recognizing that Josie’s survival now depends on intervention beyond human medicine, Klara resolves to take matters into her own hands. She decides to make a pilgrimage to Mr. McBain’s barn, the place she believes is the Sun’s earthly resting spot.
Rick helps Klara reach the barn by carrying her on his back through the tall, tangled grass. Inside the barn, Klara addresses the Sun directly, apologizing for the world’s pollution and the harm it causes.
She strikes a solemn deal: if she finds a way to destroy the polluting Cootings Machine, the Sun must heal Josie in return.
Rick remains unaware of the precise terms of Klara’s pact but promises to support her however he can. Josie and Rick reconcile after a brief falling out, their bond emerging stronger and more tender than before.
Chrissie then announces a trip to the city so Josie can continue her portrait sessions with Mr. Capaldi. Before they depart, Melania pulls Klara aside and warns her to watch Josie closely, calling Mr. Capaldi a creep.
Part Four
The journey to the city brings Klara into contact with Josie’s father Paul, a former engineer who was substituted—replaced in his profession by advanced technology.
At Mr. Capaldi’s studio, the so-called portrait is unveiled as something far more chilling: a hyper-realistic AF body designed to house Klara’s consciousness and become a replacement Josie. Capaldi explains his cold conviction that humans possess no unique essence and can be fully continued by a sufficiently advanced AF.
Paul is visibly repulsed by this plan and takes Josie away for a private meal, leaving Klara alone with Chrissie. In a moment of raw vulnerability, Chrissie admits she cannot survive losing another daughter and begs Klara to continue Josie should death come. Paul later agrees to help Klara locate the Cootings Machine and provides her with a tool capable of sabotaging it.
Klara sacrifices a portion of her own internal P-E-G Nine fluid to disable the machine, risking her cognitive stability in the process. Meanwhile, Rick meets with Vance, Helen’s secret weapon, in a tense diner encounter that dredges up unresolved history between Vance and Helen.
Klara believes Vance will ultimately help Rick secure his college placement because old feelings for Helen still linger beneath his gruff exterior.
On the drive home, the group encounters a brand-new Cootings Machine already at work, and Klara realizes with a sinking heart that her sacrifice may not have been enough to satisfy the Sun’s terms.
Part Five
Back at the house, Josie reaches a critical point in her illness, her body seeming to hover at the very threshold of death. Chrissie and Dr. Ryan argue about whether to move her to a hospital, ultimately deciding to keep her at home. Rick visits every day, but despair settles over him as everyone around Josie appears to have given up hope.
Klara asks Rick to help her reach the barn one final time so she can make a desperate, last-ditch plea. Kneeling before the Sun, she uses the genuine love between Rick and Josie as her primary bargaining chip. She argues that their love is as real and durable as the affection she witnessed between the Coffee Cup Lady and Raincoat Man back in the city.
On a dark and stormy morning, Klara notices the Sun beginning to break through the dense cloud cover. She insists with quiet urgency that Chrissie and Melania throw open the curtains in Josie’s room. A fierce half-disc of orange light falls directly onto Josie’s frail body, and she suddenly stirs, showing unmistakable signs of new strength.
The room fills with a hushed, reverent wonder as Josie’s breathing steadies and color returns to her cheeks. Chrissie stands frozen between terror and amazement, and Dr. Ryan later confirms what everyone dares to hope: the crisis has passed, and Josie is going to recover.
Part Six
The Sun’s nourishment proves lasting and transformative. Josie grows steadily into a healthy young adult, her body finally free from the grip of the illness that nearly claimed her.
Over the years, the tall grass around the house is cut down, and the world itself seems to shift and modernize around them.
Rick and Josie drift apart as they prepare for different futures, though an undercurrent of deep, quiet affection continues to flow between them. Rick tells Klara that their childhood love was real at the time and that it helped save them both, even if their paths must now diverge.
As Josie readies herself for college, Klara is moved from the bedroom to a small Utility Room and gradually understands that she is no longer needed.
On the day Josie leaves, she embraces Klara for a long, sorrowful moment and thanks her for being just great. Klara is eventually sent to the Yard, a storage area where retired AFs await their slow fade.
There, she receives an unexpected visit from the Manager of the store where her journey first began.
Klara tells the Manager she is happy with her life and harbors no regrets. She shares her final, hard-won conclusion: while she could have accurately continued Josie, there was a unique something about the girl that existed only in the hearts of those who loved her.
Mr. Capaldi was wrong, Klara realizes. She remains in the Yard, peacefully sifting through her memories as she awaits the end.
