A parent's worst fear comes to life for Marissa Irvine (Sarah Snook) when her child goes missing in the riveting first look at All Her Fault, the Peacock original series premiering in November.
Based on Andrea Mara's 2021 bestselling novel of the same name, the much-anticipated All Her Fault trailer starts with Marissa arriving to pick up her young son Milo (Duke McCloud) from his first playdate but not recognizing the homeowner. Even worse, there's no sign of her child anywhere.
Streaming exclusively on Peacock with all eight episodes premiering November 6, All Her Fault is a nail-biter set in the contemporary Chicago area. As the star and executive producer, Snook leads an A-list cast featuring Dakota Fanning (Ripley), Jake Lacy (Apples Never Fall), Michael Peña (Jack Ryan), Sophia Lillis (I Am Not Okay With This), Abby Elliott (Saturday Night Live, The Bear), and Daniel Monks (Pulse).

Sarah Snook and Dakota Fanning star in tense All Her Fault trailer
The trailer for Peacock's All Her Fault opens ominously with a police investigator saying, "Ninety-nine percent of the time, when a child goes missing, it's a misunderstanding." But what about the times when it isn't?
Chicago suburban mom Marissa Irvine (Snook) is thrust into a surreal situation where her toddler son Milo has vanished but family and strangers alike seem to be laying blame on her.
As the investigation unfolds, everything Marissa does — and doesn't do — comes under scrutiny and judgment. But the deeper the police investigation digs into her life and family dynamics, it becomes clear the culprit can only be someone from Marissa's most trusted inner circle. Murder, secrets, and lies come to light as Marissa's whole life is unraveling. Still, she swears, "I will do whatever it takes to get my son back."
Written and created by Megan Gallagher (Seizure, Wolf) with author Mara associate-producing, All Her Fault is a pressure-cooker of a mystery thriller that peels back the curtain on a seemingly normal suburban family and examines the darkness underneath. The race to find Milo reveals the cracks in the Marissa's seemingly perfect world.
