Sarah Snook stars as Marissa Irvine, a mother whose 5-year-old son vanishes during what should have been a simple playdate, in the tense Peacock miniseries All Her Fault, adapted from Andrea Mara’s novel of the same name.
At the beginning of the series, Marissa goes to pick up her son from an after-school playdate at Jenny’s house. But when she arrives, a stranger named Esther answers the door. Esther insists she doesn’t know anyone named Jenny — or Marissa’s little boy, Milo. Panic sets in as Marissa realizes something is terribly wrong.
The situation spirals into a psychological nightmare. Though Milo’s backpack contains an electronic tracker, it has mysteriously been disabled, adding another layer of tension to the story.
Sarah Snook’s acting range has long been recognized. She earned an Emmy for portraying Shiv Roy in Succession, where she embodied one of television’s most complex power players.
On stage, she won a Tony Award for her ambitious one-woman performance in The Picture of Dorian Gray, where she portrayed 26 distinct characters.
In All Her Fault, Snook channels that same intensity into a single role, delivering a performance that grips the viewer from the very first moment.
“Right from the opening scene, it’s a dramatic and challenging role, and she pulls you right in.”
The show blends psychological suspense with emotional depth, exploring maternal fear, trust, and the unraveling of reality when a child goes missing. Every scene builds a sense of panic and confusion that reflects Marissa’s deteriorating sense of control.
A mother’s frantic search for her lost son unfolds into a haunting psychological mystery, powered by Sarah Snook’s commanding screen presence and emotional realism.
