All Her Fault Season 1: Release date & time, where to watch, and what to expect

Inspired by Andrea Mara’s novel of the same name, All Her Fault season 1 is set to premiere on Thursday, November 6, 2025, on Peacock. Created by Megan Gallagher, this newly added mystery thriller is led by Succession actress, Sarah Snook, whose life is turned upside down when her kid goes missing out of nowhere. 

Sarah, who plays Marissa Irvine, shows up at the door saying, ‘’Hi. I am Marissa. I am here to pick up my son Milo.’’ Well, in response, the lady replies, “There’s no Milo here.’’ And that’s when her life takes a drastic turn, where a mother loses her child, and she takes on the responsibility to find him at any cost. 

The official synopsis of All Her Fault season 1 reads, 

“In Chicago, Marissa Irvine arrives at 14 Arthur Avenue, expecting to pick up her young son Milo from his first playdate with a boy at his new school. But the woman who answers the door isn’t a mother she recognizes. She isn’t the nanny. She doesn’t have Milo. And so begins every parent’s worst nightmare.”

The family Marissa talks about doesn’t live at that house at all. In fact, the address she was given turns out to be completely wrong. It’s as if the place where her son was supposed to be for the playdate never existed in the first place.
