8ms
Prepare yourself for a chilling mystery. All Her Fault, the gripping limited series event for Peacock starring the phenomenal Sarah Snook, is here. Based on Andrea Mara's electrifying novel, this is a story that will grip you from the very first moment and refuse to let go.
Imagine this: Marissa Irvine arrives to pick up her son, Milo, from his first playdate at his new school. But the woman who answers the door… she’s never heard of Milo. She’s never heard of Marissa. It’s a parent’s deepest, darkest fear come to life. As Marissa and her husband Peter plunge into a desperate search for their son, their family begins to fracture. Their only lifeline? A new friend, Jenny Kaminski, who becomes an unlikely, yet crucial, ally. Together, these two women embark on a relentless hunt for Milo, unearthing buried family secrets that will irrevocably change the course of their lives. Meanwhile, Detective Alcaras is tasked with finding Milo and bringing the perpetrators to justice, navigating a tangled web of deception that pushes his own moral boundaries to the absolute limit.
Leading the charge is Sarah Snook as Marissa Irvine, a self-made wealth manager whose world implodes with her son's disappearance. Jake Lacy plays Peter Irvine, Marissa's husband, a commodities trader carrying his own burdens. Sophia Lillis is Carrie Finch, Jenny and Richie's nanny, accused of a shocking crime. Abby Elliott embodies Lia Irvine, Peter's sister, while Jay Ellis is Colin Dobbs, Marissa's trusted best friend and business partner. Daniel Monks portrays Brian Irvine, Peter and Lia's brother, a day trader with a unique perspective. And then there's Duke McCloud as the precious 5-year-old, Milo Irvine. Dakota Fanning shines as Jenny Kaminski, a fellow mom whose son is friends with Milo, and a force to be reckoned with as head of marketing at Blackhorn. Rounding out the main cast is Michael Peña as Detective Alcaras, the seasoned detective trying to piece together this terrifying puzzle.
The series also features a compelling supporting cast, including Melanie Vallejo as Sarah Larsen, Tayden Jax Ryan as Jacob Kaminski, Thomas Cocquerel as Richie Kaminski, Kartiah Vergara as Ana Garcia, Joey Vieira as Victor Beran, Laura Brent, Aimee Babich, Johnny Carr as Detective Greco, and Orlando Ivanovic as Sam Alcaras.
All Her Fault is the brainchild of writer, creator, and executive producer Megan Gallagher, bringing Andrea Mara's best-selling novel to life. Sarah Snook not only stars but also serves as an executive producer, alongside Minkie Spiro, Nigel Marchant, Gareth Neame, Joanna Strevens, Jennifer Gabler Rawlings, and Christine A. Sacani. The series producer is Terry Gould, with Kate Dennis also directing multiple episodes.
Filming took place in the vibrant city of Melbourne in August 2024, bringing this intense story to life.
The series premiered on November 6, 2025, and critics are raving. Rotten Tomatoes reports a strong 79% approval rating, calling it "a twisty thriller that underscores the societal pressures placed on working mothers, an addicting watch thanks largely to Sarah Snook and Dakota Fanning's emotionally grounded performances." Metacritic, meanwhile, awards it a score of 60 out of 100, indicating generally positive reviews.
