Don’t Let Her Stay Summary: Full Story Breakdown
Spoilers ahead. This section recounts the complete plot, including the ending and final twist.
Part One: Arrival and Isolation
Joanne Atkinson lives in a secluded country estate near Chertsey with her husband Richard, a wealthy boutique investment banker, their four-month-old daughter Evie, and a caramel Labrador named Oscar.
Joanne is exhausted by Evie’s refusal to sleep and feels isolated from her former life as a working-class estate agent.
A handwritten letter arrives for Richard from Chloe, his twenty-one-year-old daughter from his first marriage. Chloe had cut off contact eighteen months earlier after refusing to attend Richard and Joanne’s wedding. Richard is overjoyed at the prospect of reconciliation.
Chloe arrives with a demeanor of subtle hostility toward Joanne. She makes passive-aggressive remarks about Joanne’s appearance, age, and inability to breastfeed.
When Joanne hires a nanny named Paula, Chloe offers to act as Evie’s nanny instead. Richard enthusiastically accepts and insists Joanne cancel Paula.
Part Two: Escalating Manipulation
Chloe’s behavior escalates into active psychological sabotage. She wanders off during a village trip, leaving the pram unattended.
She panics while holding Evie and flees the room screaming. Late one night, Joanne finds the baby monitor off and Chloe holding a broken bottle of infant Calpol in the dark nursery.
Richard takes Chloe’s side each time, scolding Joanne for being out of control. He suggests Joanne’s exhaustion and forgetfulness mirror her mother’s history of postpartum psychosis. Joanne begins to doubt her own perceptions.
Chloe vanishes during Joanne’s work video calls, disrupts her job, and blackmails her with a Photoshopped photograph showing Joanne kissing the gardener Simon.
When Joanne confronts her, Chloe threatens to show the image to the possessive Richard unless Joanne lets her remain as nanny.
Part Three: Investigation and Confrontation
Desperate to verify her sanity, Joanne sends the Calpol for toxicology testing and installs hidden wireless security cameras. The lab report confirms the liquid was harmless.
The hidden footage shows Chloe acting gentle when alone with Evie, singing a nursery rhyme.
Chloe discovers one of the camera cubes and shows it to Richard. He smashes a glass, accuses Joanne of spying, and reveals that his first wife Diane did not die of cancer but fell from a third-floor balustrade in a death ruled a suicide.
Joanne consults her GP and confides in her lawyer best friend Robyn, who urges her to trust her instincts. Joanne finds a news article stating police treated Diane’s death as suspicious. Richard then reveals another secret: he and Diane had a second daughter, Sophie, who died of cot death at three months.
Joanne contacts Jim Preston, the retired journalist who wrote the original reports. Jim reveals that eleven-year-old Chloe initially claimed an intruder was present during her mother’s death before recanting.
All house phones had been unplugged, and Richard appeared terrified of his daughter.
Part Four: The Climax and Final Twist
Richard leaves for a business trip to Amsterdam and arranges for the cleaner Roxanne to stay overnight. The solicitor Solomon calls Joanne, asking about a call Chloe made inquiring about Richard’s will.
Chloe then holds Evie at an open window and claims Richard murdered Diane and plans to kill them for insurance money.
Richard suddenly appears in the house, which now smells of petrol. He retrieves an axe and breaks down doors while Joanne, Chloe, and Evie flee into the basement. Richard hunts them through the burning house with a shotgun. Oscar attacks Richard, and Chloe snatches the shotgun and shoots him dead.
Two months later, Joanne and Chloe are living together in Islington like close sisters.
Joanne visits Diane’s elderly mother Helen, who reveals the truth: Chloe pushed Diane, poisoned baby Sophie, and manipulated Joanne into viewing Richard as the killer so Joanne would serve as an innocent witness.
Chloe had texted Roxanne to cancel, poured the petrol, and locked the doors herself.
As Chloe returns with jam, Helen grips Joanne’s arm and whispers her final warning: “Don’t let her stay.”
