All Her Fault Episodes – Complete Guide and Summaries
Searches for all her fault episodes reveal a suspenseful limited series available on Peacock and Sky Atlantic, rather than the true crime podcast some listeners expect. The eight-episode thriller, adapted from Andrea Mara’s 2021 novel, stars Sarah Snook as Marissa Irvine, a mother whose five-year-old son vanishes after a playdate, unraveling a six-year-old conspiracy of swapped infants and calculated revenge.
Despite trending queries that suggest connections to real criminal cases, All Her Fault is entirely fictional. The narrative centers on the affluent Irvine family—Marissa, her husband Peter, and their missing son Milo—whose disappearance exposes secrets linking a car crash, a kidnapping, and multiple deaths in a Chicago suburb.
The series employs a non-linear structure, with crucial revelations delivered in a flashback-heavy seventh episode that recontextualizes the preceding investigation. Understanding the episode sequence and streaming availability helps viewers navigate the complex timeline and interpret the finale’s morally ambiguous resolution.

Complete Episode Guide and Summaries
The All Her Fault Episode Guide confirms eight distinct installments, each advancing the dual timeline of present-day investigation and past secrets. The series relies heavily on the seventh episode’s flashback structure to resolve its central mysteries.
Episode 1: The Disappearance
The premiere establishes 1800 Crescent Road as the inciting location. Marissa Irvine arrives to collect her son Milo from a playdate at neighbor Jenny Kasinski’s home, only to find the child missing. The installment introduces the high-powered professional lives of the Irvines, the immediate community shock, and the initial police response led by Detective Alcaras. Viewers can find detailed spoilers for this opening chapter through Peacock’s official Episode 1 breakdown.
Episodes 2-6: The Investigation Deepens
The middle installments build suspense through media scrutiny, widening police searches, and the revelation of interpersonal betrayals among the suburban parents. These episodes focus on the fallout from the playdate, emerging suspects, and the gradual unraveling of Peter Irvine’s carefully constructed life. Community reactions and law enforcement procedures dominate the narrative, with each chapter ending on cliffhangers regarding potential sightings or new evidence.
Episode 7 reveals that Carrie Finch (operating under the alias Josephine) kidnapped Milo as direct vengeance for a baby swap that occurred six years prior. During a car crash, Peter Irvine exchanged their deceased infant for Carrie’s surviving son (Milo), creating the biological relationship that drives the kidnapping and subsequent deaths of Kyle, Rob, Carrie, and Colin.
Episode 7: The Revelation
Functioning as the narrative’s structural centerpiece, this flashback episode travels six years into the past to depict the fatal car crash. It identifies Carrie Finch as the kidnapper and traces her systematic plan for revenge, including ransom schemes and targeted violence. The installment recontextualizes every previous clue, revealing that Milo’s biological mother is actually Carrie, not Marissa.
Episode 8: The Finale
The final episode brings confrontations to a head as Marissa learns the complete truth via recording devices. Discovering Peter’s role in the deaths of multiple people, she utilizes his severe soy allergy to poison him. The Detective closes the case without full prosecution of Marissa, leaving the legal and moral resolution ambiguous. YouTube recaps of this finale highlight the “trash husband” trope and Carrie’s body count as central to viewer reactions.

Understanding the Narrative: Plot Mechanics and Themes
Beyond the procedural elements of the investigation, the series explores themes of maternal identity, marital betrayal, and the lengths parents will travel to protect—or avenge—their children.

The Baby Swap Conceit
The central twist hinges on a biological substitution made during trauma. When Peter and Marissa’s infant dies in a car collision six years before the main events, Peter swaps the body with the surviving child of the other driver, Carrie Finch. This act—hidden until Episode 7—creates the false identity of “Milo” and sets in motion the kidnapping and murders that follow.
The series streams exclusively on Peacock in the United States and on Sky Atlantic/NOW in the United Kingdom. No additional streaming platforms currently carry the content, and no broadcast television syndication has been announced.
Maternal Vengeance and Justice
The finale complicates traditional morality by positioning Marissa as both victim and perpetrator. Upon learning that Peter’s lie caused five deaths—including those of friends and the kidnapper herself—she chooses lethal retribution. The narrative closes with Detective Alcaras aware of her guilt but declining full prosecution, suggesting a system that excuses certain crimes of passion.
While the series presents episodes sequentially, first-time viewers should resist the urge to skip ahead to Episode 7. The flashback structure relies on accumulated context from Episodes 1-6 to achieve its intended emotional impact regarding the baby swap revelation.
Episode Release and Narrative Timeline
Unlike traditional weekly releases, the eight episodes debuted simultaneously as a binge-ready limited series. However, the story’s internal chronology follows a specific trajectory:
- Six Years Prior: The car crash on State Route 41 results in infant death; Peter Irvine executes the baby swap with Carrie Finch’s surviving son (depicted in Episode 7).
- Day One (Morning): Marissa drops Milo at 1800 Crescent Road for the fateful playdate with Jenny Kasinski’s children.
- Day One (Afternoon): The disappearance is discovered when Milo cannot be located at the neighbor’s home; Detective Alcaras initiates the investigation (Episode 1).
- Days Two Through Six: Police interrogation, media coverage, and the uncovering of Jenny Kasinski’s suspicious behavior dominate the investigation (Episodes 2-6).
- Day Seven: The confrontation at the Finch residence reveals Milo’s true parentage; Carrie’s death occurs during the rescue attempt.
- Day Seven (Evening): Marissa poisons Peter using his soy allergy; the Detective formally closes the case despite knowledge of her involvement (Episode 8).
