Peacock’s psychological thriller “All Her Fault” concluded its first season with jaw-dropping revelations that upended everything viewers thought they knew. The limited series, based on Andrea Mara’s bestselling novel, stars Sarah Snook as Marissa Irvine, a mother whose life descends into chaos when her five-year-old son Milo disappears during what was meant to be his first playdate.
The truth behind Milo’s disappearance unraveled into a twisted tale of family secrets spanning years, multiple deaths, and the crumbling foundation of the Irvine family. Here’s a breakdown of how “All Her Fault” wrapped up — and the significance of those final moments.
Milo’s kidnapping serves as the catalyst for the entire series. When Marissa arrives to pick him up from Jenny’s house, she learns that there was never a playdate planned and her son is missing.
In the finale, it is revealed that Carrie, the nanny hired by Jenny, orchestrated Milo’s abduction. Alongside her criminal ex-boyfriend Kyle and her father Rob, Carrie kidnapped Milo from his school. Peter, Milo’s father, tracks down the kidnappers at a motel, confronts them with ransom money, and saves Milo. However, it is then revealed that Milo is not actually Peter and Marissa’s biological child, but rather Josie’s, who had lost her own child in a car crash involving Peter and Marissa six years prior.
The show dives deeper into Peter’s dark past, revealing his involvement in multiple deaths and cover-ups, including an accident that left his brother disabled. Despite the heinous acts he perpetrated, Marissa decides not to turn him in. However, at Colin’s funeral, Peter suffers a fatal anaphylactic shock due to Marissa’s deliberate actions.
Detective Alcaras, who has been investigating Milo’s case, pieces together the truth and decides to close the case to spare more pain. The series ends with Marissa and Jenny watching their sons play together in a peaceful moment after the chaos.
While the possibility of a second season remains uncertain, showrunner Megan Gallagher expressed openness to the idea. For now, viewers can immerse themselves in all eight gripping episodes of “All Her Fault” on Peacock.
As the series came to a close, the haunting themes of secrets, betrayal, and redemption linger in the air, leaving audiences with a powerful and thought-provoking conclusion.
