Pregnant attorney Caitlyn Morales [Mary Elizabeth Winstead] is assigned to represent Polly Murphy [Maika Monroe], a young woman facing eviction and homelessness. Shortly after their first meeting, Caitlyn gives birth to her second daughter, Josie [Lola Contreras], while juggling the demands of motherhood, a demanding career, and her volatile older child, Emma [Mileiah Vega]. When the women meet again, Polly asks for employment as the family’s nanny, and she quickly becomes indispensable, charming both Emma and Caitlyn’s husband, Miguel Morales [Raúl Castillo], with warmth and attentiveness. Yet beneath Polly’s poised exterior lurks something more sinister.
She secretly poisons Caitlyn and the children by spiking a seafood stew, making their illness seem accidental. Grateful for Polly’s continued help, Caitlyn and Miguel invite Polly to live in their guest house, allowing her to discreetly overstep boundaries. Polly discovers that Caitlyn takes medication for an unspecified mental condition and, cooking up a more terrible scheme, replaces the pills with carved methamphetamine tablets, gradually destabilizing Caitlyn’s grip on reality. Paranoia, irritability, and jealousy about Polly’s growing influence over Emma begin to erode Caitlyn from within.
When Emma accidentally ignites fireworks that Polly had supplied, Caitlyn lashes out and fires Polly, despite Miguel’s pleas for mercy. Wracked with guilt and desperate to keep Emma from further zealotry toward Polly, Caitlyn tracks Polly to a dilapidated motel and rehires her. She also enlists her neighbor, Stewart [Martin Starr], to investigate Polly’s past, and contacts a supposed former employer listed as a reference, learning that Polly had met Polly’s own fabricated story of abuse at an Alcoholics Anonymous meeting.
Stewart confronts Polly with the results of his background check, revealing that Polly’s true name is Rebecca, and that both she and Caitlyn—whose real name is Jennifer—share a dark, intertwined history. Years earlier in San Bernardino, a fire set by young Jennifer had destroyed Rebecca’s home, killing her parents and infant sister. Jennifer was given a new identity, while Rebecca endured years of trauma in abusive foster homes. Although Stewart urges forgiveness, Polly kills him with a baseball bat, stealing his research before fleeing.
Caitlyn learns of Stewart’s assault and rushes home, only to find Polly calmly dining with Miguel and the children while dressed in Caitlyn’s clothes. Enraged, Caitlyn destroys Polly’s belongings and lunges at her, accidentally striking Emma during the confrontation. Miguel, horrified, expels Caitlyn from the house and files domestic-violence charges, barring her from seeing her daughters unsupervised. Desperate, Caitlyn later appears at Emma’s basketball game and pleads for reconciliation. Emma forgives her and secretly returns Stewart’s documents which she had stolen from Polly. A childhood photograph of Polly triggers Caitlyn’s memory, and she recognizes Polly as the surviving child from the fire.
Racing home, Caitlyn finds Polly fully transformed into her double, even mimicking her hairstyle and mannerisms. The two share a tense kitchen showdown. Caitlyn confesses that she set the fire not out of malice but to escape Polly’s father, who had sexually abused both girls. Polly doubts her sincerity but acknowledges that, true or not, Caitlyn robbed her of a family and any chance at happiness. Caitlyn attempts to embrace Polly, but Polly shatters a glass and stabs her, declaring her intent to assume Caitlyn’s life and raise her children as her own. A violent struggle follows, culminating with Caitlyn pushing Polly through a plate-glass window. As Caitlyn flees with Josie, Polly attacks their car, sending Caitlyn into oncoming traffic. The crash leaves Caitlyn and Josie dazed, while Polly sustains fatal injuries. Witnessing the commotion, Miguel arrives with Emma and apologizes for doubting Caitlyn. Caitlyn holds Polly in her final moments.
Later, Caitlyn stares into a lit fire, haunted but alive. Nearby, Emma imitates Polly’s gestures and repeats one of her stories about life in foster care, soothing her baby sister.

In the climax Caitlyn finally confronts the nanny who has been systematically tearing her family apart. Polly’s violent act of murdering Stewart – the friend who unearthed her tragic past – drives Caitlyn over the edge, and a frantic struggle erupts between the two women. When Polly’s bond with little Emma forces the child to defend her, Caitlyn unintentionally strikes her own daughter, shattering the fragile trust that had held the household together. This loss of composure forces Caitlyn to sit down with Polly, the very woman who has been living in her house, hoping a desperate conversation might end the nightmare.
The discussion quickly turns dark. Caitlyn reveals that both women share a history of sexual abuse: Polly’s father tormented her, and the same man had once assaulted Caitlyn when they were children. Caitlyn admits that, as a teen, she set fire to the house that killed Polly’s mother and sister – a secret revenge that has haunted her ever since. Polly, enraged by the revelation, stabs Caitlyn in the abdomen. The two continue to grapple, and Caitlyn manages to pull her younger daughter Josie into the car and reverse out of the driveway. Polly leaps onto the hood, trying to break the windshield, just as Miguel and Emma arrive. A speeding neighbor’s car crashes into Caitlyn’s vehicle, hurling Polly onto the pavement where she bleeds out. In her final moments Caitlyn cradles Polly’s head, a quiet acknowledgement that their pain was intertwined.
Months later the scene shifts to a quiet evening by the fireplace. Caitlyn, now nursing the scar on her hand from the fight, asks Miguel where Emma is. He tells her Emma is with Josie, and the children are safe. Emma appears, silently reciting the story Polly once told her about surviving on canned tuna, a detail that signals Polly’s world‑view has seeped into the girls. Though Polly is dead, the film suggests that her attitudes toward class, survival, and identity have been passed down to Emma and may shape Josie as they grow. The ending leaves Caitlyn confronting the consequences of her past actions while the next generation carries forward the fragile legacy of the woman who came to their home seeking vengeance.
