If you were a fan of ITV's Playing Nice or Disney+'s more recent offering, The Stolen Girl, we've found a chilling new suburban thriller you'll want to add to your watch list. All Her Fault is the new Sky thriller series about a playdate that goes very wrong - and let's just say it will make you question your childcare.

Set to arrive on our screens later this year, the series stars Succession’s Sarah Snook as Marissa Irvine, who sends her son, Milo, off for a "playdate" that turns out to be far from straightforward. When she goes to pick Milo up from her new friend’s house, she discovers that the people living there have never heard of him.

The eight-part series – filmed in Melbourne - is based on the bestselling novel of the same name by Andrea Mara, which was a huge hit with fans, and we have a feeling the TV adaptation is going to be just as popular. Ahead of the All Her Fault's arrival on our screens, here's everything you need to know about the series, including the plot, cast and how to watch it.

As we mentioned, the series revolves around mother Marissa Irvine, who arrives at a house to collect her son, Milo, from a playdate with a new friend. So far, so straightforward - only the woman who answers the door isn't who she's expecting. In fact, she doesn’t recognise her at all. Not only does this woman not have Milo, she claims to have never heard of him.

As news of Milo's disappearance ripples through the wealthy community, time is of the essence to find him and an unexpected suspect is named – but as people become eager to find someone to blame, rumours and gossip about all the women involved start to grow. Only one of them could have taken Milo, after all – or perhaps all of them are at fault?

Katie Keenan, Group Director of Acquisitions for Sky UK and Europe, has described the series as a "twisty" suburban thriller and says it "promises to be a huge fan-favourite". And with Succession's Sarah Snook leading the cast, something tells us she's right!.
