‘All Her Fault’ on Peacock: Cast, Episodes, and How It Connects to ‘Succession’

Peacock’s new limited series All Her Fault has arrived—and it’s already a buzzy binge. Based on Andrea Mara’s novel of the same name (often searched as It’s All Her Fault), the thriller follows a mother whose quick stop to collect her son from a playdate spirals into a nightmare. If you’re searching “all her fault cast,” “Peacock,” or “episodes,” here’s the fast, spoiler-light guide.

What is ‘All Her Fault’ about?

Set in suburban Chicago, the story centers on Marissa Irvine, a high-achieving parent who arrives for her child’s playdate pickup and meets a woman who swears she’s never heard of Marissa’s son. From there, the eight-episode mystery digs into panic, secrets, and shifting alliances among parents, friends, and neighbors—keeping the focus on modern motherhood and the pressures that come with it.

Why ‘All Her Fault’ is trending with ‘Succession’ fans

Two big reasons:

1. Sarah Snook anchors the show with a controlled, steel-nerved performance that fans of Shiv Roy will instantly recognize—minus the corporate boardrooms.

2. The series favors smart character work over shock-for-shock’s-sake plotting, channeling tension through power dynamics inside a marriage, a friend group, and a neighborhood.

Is ‘All Her Fault’ based on a true story?

The series adapts Andrea Mara’s 2021 novel. While the plot is fictional, the inciting “wrong address” panic was sparked by a real-life mix-up the author once experienced. The show leans into the “what if” nightmare that scenario might unleash.
