All Her Fault: From Succession to a Mother’s Nightmare – Snook’s Haunting Turn in a Twisty Kidnapping Saga That Blends Sharp Objects Paranoia with Big Little Lies Betrayal

Watch All Her Fault | Peacock

 November 17, 2025 – It begins with a mother’s scream echoing through a pristine Chicago suburb—and ends with a secret that could obliterate everything in its path. Peacock’s All Her Fault, the eight-episode psychological thriller that premiered on November 6, stars Sarah Snook in her most harrowing role yet as Marissa Irvine, a high-powered wealth manager whose world implodes when her five-year-old son, Milo, vanishes from his first playdate. What follows is a labyrinth of lies, guilt, and buried betrayals that spirals into obsession and paranoia, leaving viewers shattered and questioning every neighbor’s smile. Adapted from Andrea Mara’s 2021 bestseller by creator Megan Gallagher (Wolf), this Peacock Original isn’t just a missing-child thriller—it’s a razor-sharp dissection of maternal terror, societal privilege, and the darkness lurking behind manicured lawns. With Snook joined by Dakota Fanning and Jake Lacy, the series collides The Stolen Girl‘s raw desperation with Sharp Objects‘ Southern Gothic unease, delivering a storm of emotional carnage that grips from frame one and refuses to release until the credits roll.

The nightmare ignites in Episode 1: Marissa arrives at 1800 Crescent Hollow Road, a sprawling McMansion in an elite enclave, expecting to scoop Milo from a classmate’s playdate. The woman who answers—polite, puzzled—has never seen him, never heard his name. Panic surges as Marissa dials Jenny (Fanning), the harried mom who arranged the meetup; Jenny swears Milo never arrived. Cue the unraveling: Marissa’s husband Peter (Lacy), a charming but evasive tech exec, races home from a “business trip,” while Detective Alcaras (Michael Peña) leads a frantic search that unearths suburban skeletons. Every whisper from nosy neighbors feels like a threat; every half-remembered detail a potential clue—or lie. As Marissa pores over security footage and interrogates playgroup parents, the series peels back the facade of upper-middle-class bliss: passive-aggressive PTA wars, hidden addictions, and the crushing weight of “having it all” on working mothers like Marissa, whose career highs mask a marriage fraying at the edges.

Snook, fresh off her Emmy-winning Shiv Roy in Succession, channels that icy ambition into maternal ferocity, her wide eyes and trembling lip conveying a woman teetering on madness. “Marissa’s not just looking for her son—she’s excavating her own buried self,” Snook told Variety at the premiere, crediting Gallagher’s script for flipping the “hysterical woman” trope into a force of reckoning. Fanning’s Jenny is a powder keg of quiet desperation, her unraveling facade hinting at secrets that twist the plot like a knife. Lacy’s Peter slithers through charm and gaslighting, while Peña’s Alcaras brings weary gravitas to a cop haunted by unsolved cases. Standouts include Sophia Lillis as the enigmatic nanny Carrie, whose mid-season bombshell reframes the entire mystery, and Abby Elliott as the judgmental school mom whose microaggressions mask deeper malice.

Gallagher, drawing from Mara’s novel, crafts a narrative that’s elegant on the surface but brutal underneath—elegant dinner parties devolving into interrogations, playground chats laced with suspicion. Directed by Minkie Spiro (3 Body Problem) and Kate Dennis (The Handmaid’s Tale), the visuals are a study in suburban claustrophobia: wide-angle lenses distort picket fences into prisons, shadows creep across pristine kitchens. Nathan Barr’s score throbs with dissonant strings, amplifying the dread of everyday horrors.

Critics are captivated: Rotten Tomatoes holds at 77%, with The Guardian praising its “brilliant balance of thriller pace and social bite.” The Hollywood Reporter calls it “addictingly twisty, anchored by Snook’s powerhouse performance.” Viewers? Obsessed and overwhelmed. “Paused Episode 4 sobbing—how do we blame a mom for surviving?” one tweeted, while another confessed: “Finished at 3 a.m., stared at the wall for an hour. 10/10 brain hijack.” Peacock reports 22 million hours viewed in the first week, outpacing The Perfect Couple.

All Her Fault doesn’t just ask who took Milo—it probes what we’d do to get him back, exposing the beasts we all harbor. Eight breathtaking episodes tighten their grip until the final frame, where nothing—and no one—is as it seems. Sarah Snook’s magnetic turn, merciless twists, and unbearable emotion make this a must-watch nightmare. If you think you’re ready for the truth—you’re not. Stream on Peacock. Watch below… if you dare.
