The psychological thriller All Her Fault has become a major topic of conversation, blending a parent’s worst nightmare with shocking family secrets. If you are looking to watch the buzz-worthy series starring Sarah Snook, here is your complete guide to where it is streaming, when it airs on TV, and what the gripping story is about.
All eight episodes of the limited series are available to stream right now on Peacock. The show first premiered on the platform on November 6, 2025. It quickly gained popularity, with reports indicating it was watched for over 46 million hours.
For viewers who prefer other services, the series is also available for purchase. You can buy individual episodes or the full season through digital retailers like Amazon Prime Video. Checking the video store on your smart TV, gaming console, or cable box will likely show it available for on-demand rental or purchase.
The series is also airing on traditional television. All Her Fault made its broadcast debut on NBC on December 4, 2025. New episodes continue to air weekly.
This broadcast run is a chance for viewers without Peacock subscriptions to follow the mystery as it unfolds.
All Her Fault is based on the novel by Andrea Mara. The story begins when businesswoman Marissa Irvine (Sarah Snook) goes to pick up her five-year-old son, Milo (Duke McCloud), from a playdate. She arrives at the given address only to find a stranger who has never heard of Milo or the playdate. This moment sparks a frantic search that unravels dark secrets within her family and community.
The series features a strong ensemble cast. Jake Lacy plays Marissa’s husband, Peter. Dakota Fanning plays Jenny Kaminski, the mother Marissa believed she was communicating with. Michael Peña stars as Detective Alcaras, who is investigating the case. Sophia Lillis plays the mysterious nanny, Carrie Finch, whose connection to Milo becomes central to the plot.
The show has received critical recognition, earning a 2026 Golden Globe nomination for Best Television Limited Series. Sarah Snook is also nominated for a Golden Globe for her performance.
Without giving away major spoilers, the search for Milo reveals that the nanny, Carrie, has a deep and unexpected fixation on the boy. As Detective Alcaras investigates, he discovers a link between Carrie and Milo: a rare neurological condition called synesthesia, which can be inherited. This clue leads to a tragic revelation about a car accident six years earlier that ties Marissa, her husband Peter, and Carrie together in a devastating way.
“It’s a real gift of a twist,” Sarah Snook said about the story’s ending in an interview with Vanity Fair. “So I couldn’t say no”.
The twists explore intense themes of motherhood, guilt, and the lengths to which people will go to protect their families. The story examines how blame is assigned, especially to mothers, when a tragedy occurs.
