Which All Her Fault Character Are You?

Learn More About All Her Fault

All Her Fault is Peacock's 2025 mystery thriller miniseries, adapted from Andrea Mara's 2021 novel of the same name and relocated from a Dublin suburb to the Chicago area for television. Across eight tightly wound episodes, it turns a single, gut-punch premise, a mother arriving to pick up her son from a playdate only to find he was never there, into a much wider examination of how blame, guilt, and public scrutiny land differently depending on who you are.

Sarah Snook, fresh off her Emmy-winning run as Shiv Roy on Succession, leads the cast as Marissa Irvine, a Chicago professional whose life implodes the moment she realizes her five-year-old son Milo is missing and that the playdate she thought she had arranged never actually happened. Snook plays Marissa's unraveling with a mix of raw panic and controlled composure that critics singled out as some of the finest work of her career, and the role earned her a Golden Globe nomination for Best Actress in a Miniseries.

Dakota Fanning plays Jenny, another mother connected to Marissa through their sons' school, who becomes entangled in the fallout the moment it becomes clear the playdate text supposedly sent from her phone was never actually hers. Fanning's performance captures the specific, modern anxiety of being publicly judged as a parent, particularly as a working mother who outsources childcare, long before anyone actually knows what happened.

Sophia Lillis plays Carrie Finch, the nanny hired to pick Milo up that day, who vanishes along with him and becomes the center of the investigation's biggest question mark. Lillis, known for roles in It and Sharp Objects, brings an unreadable stillness to Carrie that keeps viewers guessing about her real motives episode after episode.

Michael Peña's Detective Alcaraz anchors the investigation with a grounded, empathetic approach that stands in contrast to the media circus swirling around the Irvine family, while Jake Lacy plays Peter Irvine, Marissa's husband, whose steady exterior slowly reveals cracks of his own as the season progresses. Abby Elliott, Daniel Monks, and Jay Ellis round out an ensemble that keeps expanding the circle of people with something to hide.

Critics have praised the series for using its central kidnapping plot as a lens on the way society, and especially the internet, rushes to assign blame to mothers specifically, whether or not the facts support it. That thematic backbone, paired with genuinely twisty plotting, is a big part of why All Her Fault landed as one of the most talked-about limited series of its premiere season and picked up two Golden Globe nominations, including Best Limited Series.

Whether you matched with fierce, guilt-ridden Marissa, defensive Jenny, unreadable Carrie, steady Detective Alcaraz, or composed-but-hiding-something Peter, each character represents a different way people cope when their private lives are suddenly put on public trial. All eight episodes of All Her Fault are streaming now on Peacock.
