Missed 'All Her Fault' premiere on NBC? Here's how you can watch the full first season now

'All Her Fault' follows the story of Sarah Snook's Marissa Irvine, whose son Milo goes missing after a playdate

Sarah Snook's thriller series 'All Her Fault' has finally premiered on NBC. The first episode of the mystery limited series made its debut on NBC on December 4, 2025. For the unversed, the eight-episode series, based on Andrea Mara's 2021 novel of the same name, originally premiered on Peacock on November 6, 2025. Since its release, the show has impressed viewers, earning a rating of 7.6 out of 10 on IMDb; on Rotten Tomatoes, 'All Her Fault' earned an impressive 79%. Along with Snook, the show also stars Jake Lacy, Dakota Fanning, Jay Ellis, Abby Elliot, Michael Pena, Thomas Cocquerel, and Daniel Monks. 

As per Just Jared, the official synopsis of the show describes a harrowing circumstance Sarah Snook's character finds herself in. "Marissa Irvine (Sarah Snook) arrives to collect her young son Milo from his first playdate, but the woman who answers the door isn’t a mother she recognizes. She doesn’t have Milo and has never heard of him. As every parent’s worst nightmare begins to unfold, new questions lead to deep secrets, revealing cracks in the Irvine's seemingly perfect world until everything is left shattered," the synopsis reads. 

For fans wondering if 'All Her Fault' is based on a true story, the answer is no. Mara's book, 'All Her Fault', is a work of fiction. However, the story behind the novel is inspired by real-life incidents from Mara's life. As per Decider, while speaking about her book in a YouTube video, Mara said, "The book was based on a real-life event whereby I went to collect my daughter from a playdate and found myself standing outside an unoccupied house." Then, a neighbour helped out Mara by telling her that the family had moved to a new home recently, which made her realize that there was no kidnapping scenario or deadly mystery in the picture. Later in the video, Mara added, "It all ended very, very quickly. Much more quickly than it does for Marissa in the book."

In a recent interview with The Hollywood Reporter, Snook was asked to comment on the possibility of 'All Her Fault' Season 2. She said, "I don't know. [The show's] attractive[ness] in a lot of ways is that its a limited series. You come in at such a high-tension moment, and then when you leave, it seems resolved. But there is always going to be questions: How does Milo grow up in this new dynamic? When does he learn the information about his past and his parents and his true history? How does Marissa deal with that? There are no plans I'm aware of that we're going to do a second part. As Megan said about each of the characters, you could create an eight-part series on each of them. You want to see where Peter began. Why is he like that? You want to see it with Brian and Lia. Good stories can proliferate and create more.” For those who missed the NBC premiere, the first season of 'All Her Fault' is available for streaming on Peacock.
