Sarah Snook returns to television with a tightly wound, parent-focused thriller on Peacock. In All Her Fault she plays Marissa Irvine, a Chicago-based wealth manager whose life is ripped open when her five-year-old son disappears. The show promises high tension, social observation, and a star performance — and it delivers moments of each, even as its plotting and pacing often undermine the ambition.
What happens in All Her Fault: the central mystery
The series opens with a simple, terrifying moment: a mother arrives at a playdate and her child is not there. That absence launches an investigation that moves beyond a single missing kid. As detectives and family members dig in, suspicion lands on a young nanny whose presence in this affluent circle exposes fault lines. The narrative pulls viewers through interrogations, flashbacks, and strained domestic scenes as the Irvines try to piece together what happened to Milo.

Key plot beats
- Marissa notices Milo is missing after a playdate and reports it to the police.
- Detectives point to Carrie, a 21-year-old working as a nanny to another family friend.
- The investigation forces scrutiny of friends, employees, and the couple’s own choices.
- Revelations arrive late and fast, tying Milo’s disappearance to a buried backstory.
Sarah Snook’s performance: what she brings to the role
Snook carries the show with scenes of raw panic and grief. She plays Marissa’s unraveling with physical intensity and precise emotional swings. After her breakout on Succession, Snook here takes a different route: a role centered on motherhood and vulnerability rather than corporate ambition. Her work anchors many episodes and makes the viewer feel the urgency of the search.
Snook’s portrayal is the series’ strongest asset. Even when plot logic feels thin, her presence keeps attention riveted.
Supporting cast and character dynamics
The ensemble paints a picture of privilege and tension around a wealthy Midwest family. Key players include:
- Jake Lacy as Marissa’s husband, a man whose need for control complicates the couple’s response.
- Michael Peña as the lead detective, whose own life seeps into the investigation.
- Sophia Lillis as the young nanny at the center of suspicion.
- Dakota Fanning as a friend whose professional life and private guilt become focal points.
Other figures — extended relatives, household staff, and friends — circle the main family, and the series tries to mine class, gender and marital power from these interactions. Yet some supporting characters remain underdeveloped, serving the plot more than earning their own backstories.
Tone, pacing, and narrative choices
The show alternates between tense urgency and sluggish stretches. The first episodes build a claustrophobic atmosphere. Then the series slows, shifting toward long, somber scenes that focus on domestic texture. When plot twists appear, they sometimes arrive abruptly, creating a jolt rather than a satisfying reveal.
One controversial choice is withholding a crucial piece of motivation until deep in the run. That delay can feel manipulative. Instead of gradually layering causation, the series often buries essential context, only to unspool it near the end.
Thematic ambitions: motherhood, class and blame
All Her Fault aims to interrogate assumptions about working mothers and the invisible labor that surrounds childcare. The title itself points to how blame lands unevenly in crisis. In family disputes and social fallout, working mothers are often held responsible for lapses they did not cause.
- Parenting and guilt: The show explores how parental blame circulates under pressure.
- Class tensions: The presence of hired help illuminates power imbalances.
- Marriage dynamics: Spousal friction and gendered expectations are frequent triggers.
These themes are present but not always fully realized. The series nods at social critique more often than it lands an original insight.
Visual style, setting and production notes
Cinematography and location work lean into the trappings of wealth. The Irvine home functions like a character, its rooms revealing both comfort and claustrophobia. Directors Minkie Spiro and Kate Dennis use the space to heighten tension. Although the story is set in the Midwest, the production was filmed elsewhere, and wide outdoor shots betray a milder climate.
The show benefits from polished production values and costume design that underline Marissa’s curated life. Yet glossy visuals sometimes clash with the narrative’s attempt at grit.
How All Her Fault compares to similar shows
The series enters a crowded field of domestic mysteries focused on affluent women. It shares DNA with programs and books that mix social observation with suspense. Compared with some predecessors, this show leans more into melodrama than into sharp satire or moral complexity.
- Similarities: wealthy settings, relational secrets, and a slow-burn mystery.
- Differences: a greater focus on maternal anguish and a lead performance-centered approach.
Strengths and limitations
- Strengths: Snook’s central performance; strong production design; credible emotional peaks.
- Limitations: uneven pacing; late arriving explanations; undercooked secondary characters.
Where to watch and episode format
All eight episodes are available for streaming on Peacock. The show runs as a limited-series thriller, with each episode designed to advance the investigation while spotlighting different players.
