‘All Her Fault’ on Peacock: Sarah Snook and Dakota Fanning lead a twisty missing-child thriller with bite

A prestige page-turner lands on streaming with All Her Fault, a brisk, bingeable mystery that turns a parent’s worst nightmare into a razor-edged look at blame, privilege, and modern motherhood. The eight-episode limited series premiered Thursday, Nov. 6, 2025 on Peacock, adapting Andrea Mara’s bestselling novel with a sharper satirical edge and an avalanche of turns you won’t see coming.

All Her Fault cast: stacked leads, scene-stealing support

• Sarah Snook (Succession) as Marissa Irvine, a high-achieving Chicago mom whose routine playdate pickup detonates into a labyrinth of lies.

• Dakota Fanning as Jenny Kaminski, a fellow mom whose allegiance—and secrets—shift as the circle tightens.

• Jake Lacy as Peter Irvine, Marissa’s husband, a man polished enough to pass any brunch test—and slippery enough to fail the ones that matter.

• Michael Peña, Sophia Lillis, Abby Elliott, Jay Ellis, and Daniel Monks round out a neighborhood of confidants, gossips, and gatekeepers where everyone smiles—and nobody is harmless.

Creator/Showrunner: Megan Gallagher
Directors: Minkie Spiro and Kate Dennis
Episodes: 8 (approximately 46–56 minutes each)

What is ‘All Her Fault’ about?

Marissa arrives at 14 Arthur Avenue to collect her son from a classmate’s house. A stranger opens the door. No party, no child, no idea what she’s talking about. From that first misfire, the show spirals outward—into school-gate politics, HOA whisper networks, and marriages curated for Instagram. Each hour reframes the last, peeling back carefully managed personas to show what people do when their status, safety, and stories are threatened.

This isn’t procedural whodunit so much as social x-ray: a missing child case that exposes unpaid emotional labor, “default parent” dynamics, and the way institutions close ranks when reputations are on the line.

All Her Fault episodes: how to watch and what to expect

All eight episodes are available now on Peacock, designed for either a weekend binge or a nervy, night-by-night drip. The structure is intentionally kaleidoscopic—each chapter shifts POV, tightens timelines, and drops a reveal that forces you to reassess motives. Expect cliffhangers, character confessions that don’t fully compute until later, and a finale that pays off the series’ obsession with perception versus truth.

Quick viewing notes

• Format: Limited series (no filler; each hour advances the case and the social fallout).

• Tone: Suspense first, with acidic humor aimed at curated suburbia.

• Rewatch value: High. Early throwaway lines bloom into evidence once you know what to look for.

“It’s all her fault”: the title’s double sting

The phrase is both accusation and diagnosis. On its face, it’s the casual cruelty women hear when anything in the domestic sphere goes wrong. Beneath that, the series argues that blame itself is a social currency—a way to protect hierarchies by pinning chaos to one convenient woman. As the investigation widens, the title becomes a dare: whose story are we believing, and why?

Performances that cut through the calm

• Sarah Snook locates a live wire between competence and panic; even her silences read like strategy.

• Dakota Fanning plays against the expected—watch her micro-shifts as loyalties flex under pressure.

• Jake Lacy continues his run as the patron saint of plausible deniability, weaponizing decorum.

• The ensemble functions like a chorus, each neighbor adding a note of menace, empathy, or opportunism that thickens the air.

Craft & pacing: posh surfaces, prowling camera

The show’s look is glossy—glass-box kitchens, linen neutrals, tasteful pendant lights—but the camera is restless, edging around islands and stairwells as if eavesdropping. The score leans into heartbeat rhythms and clipped strings, heightening a vibe where brunch chatter can turn into testimony with one text.

How ‘All Her Fault’ reshapes the book

The adaptation keeps the novel’s set-piece shocks while expanding the social satire: more time with school administrators and charity boards, more emphasis on who gets believed first, and why. The American suburban setting amplifies the optics game—fundraisers, parent chats, curated feeds—where a missing child crisis becomes, for some, a brand risk to manage.

Should you watch?

If you loved prestige character studies with teeth—think complex women cornered by public narratives—All Her Fault is a must. It’s propulsive without cheap tricks, sharp about gendered expectations, and anchored by two leads in total control of their instruments. Start it for the mystery; stay for the way it makes everyday “niceness” feel like a threat.
