Sarah Snook Shines in “All Her Fault”: A Thrilling, Absolute Pleasure to Watch!

As a mother and someone prone to anxiety, I can become intensely paranoid, especially if one of my hormone replacement therapy patches falls off unnoticed. However, paranoia aside, the chilling story of a playdate that goes disastrously wrong in “All Her Fault” would captivate anyone. This television adaptation of Andrea Mara’s popular 2021 thriller novel masterfully intertwines several prevalent TV themes. It delves into the middle-class American affluence, reminiscent of “White Lotus,” exploring both the shield it provides and the moral decay it fosters, alongside a narrative about a missing child and the societal costs imposed on motherhood. Remarkably, it balances these elements without becoming overly didactic or letting the suspense slacken, which is a rare feat.

The story throws us directly into the midst of tension as Marissa Irvine (played by Sarah Snook of “Succession” fame), a prosperous wealth manager, goes to retrieve her five-year-old son, Milo, from a playdate at the house of another mother from school, Jenny (Dakota Fanning). However, the woman who answers the door at the address Marissa has is not Jenny, claims to have no knowledge of her or her nanny Carrie (Sophia Lillis), who was supposed to supervise the playdate, nor of Milo. It quickly becomes apparent that Milo has been missing since Carrie picked him up from school, his digital tracker destroyed in the school parking lot, and no ransom demand has surfaced.

Why? Across eight densely packed episodes that richly develop both the emotional turmoil and the fast-moving plot, a complex array of characters and potential suspects are introduced, each revealed in gradually unfolding layers. Among them is Milo’s father, Peter (Jake Lacy, known for his roles in “A Friend of the Family” and “The White Lotus”), who harbors numerous secrets. Despite his responsibilities, including caring for his younger brother Brian (Daniel Monks), left disabled from a childhood accident — an incident their sister Lia (Abby Elliott from “The Bear”) blames herself for and has struggled with addiction and rehabilitation — the show poses the question: Can any act truly be deemed altruistic, or any man genuinely virtuous? And to what extent would someone go, possibly even to abduct their own child?

During Milo’s disappearance, the Irvine’s nanny, Ana (Kartiah Vergara), oddly has taken some rare time off. Upon her return, she denies having spoken to her fellow nanny, a lie we are shown. Her employers and the police are left to consider this highly unlikely. Meanwhile, Marissa’s best friend and colleague, Colin (Jay Ellis), arrives to support the family, as does Jenny, offering sympathy and friendship in a manner that surprises both their husbands and the authorities, though not as much as Marissa’s ready acceptance of it. For women, this response might seem completely rational, though perhaps less so to men.

The two women had previously connected during an uncomfortable school social event, where they were pursued by the PTA chair, Sarah Larsen (Melanie Vallejo), a paragon of passive-aggressiveness and manipulative skill. Despite both being working mothers — a type of motherhood fraught with guilt and anger, albeit of a privileged kind — they understand each other. Jenny feels guilty for trusting Carrie (hired under her watch, though her husband feels he’d have vetted her better), but Marissa doesn’t blame her; she blames herself for everything. This sentiment is echoed by Sarah and even the wider public as news of the incident spreads. The ordeal only strengthens the bond between the mothers, a bond that also fortifies Jenny.

“All Her Fault” is executed with exceptional skill. The carefully laid plot threads all come together, and the narrative gears mesh smoothly and swiftly. You arrive drawn by the horrifying premise and remain captivated by the sheer quality of the storytelling.
