Peacock’s upcoming thriller All Her Fault asks the haunting question — how well do you really know the people closest to you?
The eight-episode limited series stars Emmy and Tony winner Sarah Snook (Succession) as Marissa Irvine, a mother whose world unravels after her young son disappears during what should’ve been a simple playdate. When Marissa shows up to pick him up, a stranger opens the door — claiming she’s never seen or even heard of her child. What follows is a tense unraveling of secrets, blame, and betrayal that will test just how far a parent will go when pushed to the edge.
The series also features Jay Ellis, Dakota Fanning, Jake Lacy, and Michael Peña alongside Sophia Lillis, Abby Elliott, and Daniel Monks.
Based on Andrea Mara’s bestselling novel, All Her Fault comes from Megan Gallagher (Wolf, Suspicion) and is directed by Minkie Spiro (3 Body Problem, Downton Abbey) and Kate Dennis (The Handmaid’s Tale).
Snook, who also serves as executive producer, called the series “a real gift of a twist.” Following her award-winning run as Shiv Roy in Succession and her Tony-winning turn in The Picture of Dorian Gray, All Her Fault marks Snook’s return to television in a role that explores motherhood, loss, and the unsettling darkness that can exist behind perfect suburban walls.
All Her Fault premieres November 6, 2025, exclusively on Peacock.
