Sarah Snook Leads a Gripping New Thriller in All Her Fault

Sarah Snook returns to the small screen with a commanding performance in All Her Fault, a tense new series that blends emotional storytelling with a tightly constructed mystery. Streaming on Peacock, the show adapts Andrea Mara’s bestselling novel into a character-driven thriller centered on a mother whose seemingly ordinary morning unravels into a life-altering crisis.

A Strong Lead Performance Anchors the Series

Snook plays Marissa, a mother whose day takes a devastating turn when she arrives at a friend’s home for a routine playdate pickup—only to discover that no one there has ever heard of her son. What begins as a moment of confusion spirals into a high-stakes search, pushing Marissa into a maze of secrets buried within her community.

The emotional weight of the role suits Snook’s range, echoing the nuance she brought to Succession while stepping into a story with a more intimate lens. Critics have praised her ability to balance fear, determination, and vulnerability as the mystery widens across each episode.

A Cast Built for Tension

The ensemble cast supports the series’ layered storytelling. Dakota Fanning delivers a sharp, unpredictable performance that keeps viewers questioning her character’s motives. Jake Lacy, Daniel Monks, Melanie Vallejo, and Orlando Ivanovic round out the cast, each adding depth to the show’s shifting perspectives.

Peter Irvine and Lia Irvine play key roles within the unfolding narrative, contributing to the story’s emotional stakes. Their interactions with Snook’s character help anchor the series in family dynamics even as the tension escalates.

A Mystery Told Through Multiple Lenses

Across its run, All Her Fault uses a structure designed to reveal the truth in careful increments. Each episode deepens the ongoing investigation, while flashbacks introduce new angles on the characters’ relationships. The pacing rewards close attention, making the series well-suited to both week-to-week viewing and full-season binging.

Peacock has organized the show into a clear episode guide, with pivotal moments in episodes 5, 6, and 7 that reshape the entire story. Themes of trust, identity, and perception surface throughout, including a character with synesthesia whose sensory experiences offer a distinctive narrative element.

Production and Storytelling Style

Filmed with a clean, atmospheric visual style, the series blends suburban normalcy with undercurrents of tension. The creative team leans on grounded performances rather than sensational twists, resulting in a thriller rooted in emotional truth.

While comparisons to other mystery dramas have surfaced—including Apples Never Fall and Long Bright River—All Her Fault stands on its own through its character-first approach and polished ensemble acting.

Ending and Narrative Resolution

The final episode delivers a resolution that ties together the show’s emotional threads while offering a clear explanation of the events driving the season’s mystery. Rather than relying on shock value, the ending focuses on accountability, perspective, and the ways people misinterpret one another’s actions.
