All Her Fault is the exact kind of “parental nightmare” thriller that makes you want to hug your kids and change your phone number. Starring Sarah Snook and Dakota Fanning, this limited series takes every parent’s worst fear and turns it into a high-stakes game of suburban secrets.

Whether you are here for the Succession star’s return to TV or just need a new twisty mystery, this guide breaks down everything you need to know about the kind of thriller that sparks immediate group chats after every episode.

What Is All Her Fault About?

Marissa Irvine (Sarah Snook) arrives at a new suburban address to pick up her young son, Milo, from his first playdate with a boy from school. When the door opens, the woman standing there is a total stranger. She isn’t Jenny, the mother Marissa talked to. She has no idea who Milo is. In fact, there is no playdate happening at all.

What follows is a desperate search that reveals the invitation was a sophisticated trap. As the investigation peels back the layers of Marissa’s social circle, it becomes clear that the abduction wasn’t random. Someone in her life has been watching, planning, and waiting for the perfect moment to make her pay for a secret she didn’t even know she was keeping.

Where to Watch All Her Fault

You can stream all episodes of All Her Fault exclusively on Peacock in the United States. For viewers in the UK, the series is available on Sky Witness and the NOW streaming service. If you are looking for other suspenseful options on these platforms, you might also enjoy the best mystery shows on Hulu or explore the best Netflix mystery shows for more late-night binging.

Is All Her Fault Worth Watching?

The Verdict: A must-watch for fans of domestic noir.

This is not a “background noise” show. If you blink, you will miss a crucial detail in the tangled web of Marissa Irvine’s life. Sarah Snook delivers a performance that is miles away from Shiv Roy. She is raw, vulnerable, and increasingly desperate.

The show succeeds because it plays on the “working mom guilt” that so many feel. It captures the social pressure of being the perfect parent in a wealthy community while your life is literally falling apart. While some of the middle episodes feel a bit stretched, the tension in the final two hours is undeniable.

Who Will Like This Show?

Some people want a slow-burn police procedural, while others want high-octane drama. Here is exactly who should move All Her Fault to the top of their watchlist:

• Fans of “Domestic Noir” and Liane Moriarty: If you loved Big Little Lies or The Husband’s Secret, you will recognize this DNA immediately. It is perfect for those who enjoy seeing the polished veneer of suburban life crack under pressure.

• The Sarah Snook Faithful: If you are experiencing Succession withdrawals, this is a mandatory watch. She brings that same high-level intensity to the role of Marissa, though her character is far more sympathetic than Shiv Roy.

• Parents Who Enjoy a Good Scare: This show taps into the primal fear of losing a child. If you like stories that make you question how well you know your neighbors or your child’s school social circle, this taps into the exact fear that makes domestic thrillers so effective: the idea that danger can exist inside ordinary routines.

• Followers of the “Unreliable Narrator” Trope: The show constantly shifts perspectives. If you enjoy a mystery where you have to decide which character is actually telling the truth, you will find plenty to analyze here.

• Binge-Watchers Looking for Quick Closure: Since this is a limited series with a definitive ending, it is ideal for a weekend marathon. You won’t be left hanging for years waiting for a second season that might never come.

If you prefer gritty, realistic crime dramas like The Wire, this might feel a bit too “glossy” for your taste. But if you want a twisty, emotional ride that keeps you guessing until the final frame, click play.
