Breaking Down the Devastating Ending of All Her Fault
All the Major Revelations in the Finale
Years of hidden deceit unravel by the time Carrie Finch, played by Sophia Lillis, raises a gun at the Irvine family in the final episode of All Her Fault. The show spans eight episodes, exploring the fine line between love and possession, and revealing how far parents will go to protect their children.
The conclusion doesn’t just solve the mystery of Milo Irvine’s disappearance after his mother, Marissa Irvine (Sarah Snook), arrives to collect him from a playdate that never happened. It uncovers the deep-seated crime that made his abduction feel inevitable, while asking what justice means when the person you fear most shares your home.
The Core Themes and Emotional Impact
The Peacock limited series centers on Milo’s kidnapping and how it shatters the lives of the Irvines, a wealthy Chicago family. Marissa’s desperate search for her son drives the story, turning what begins as a domestic thriller into a meditation on truth, control, and the fragile worlds parents build around their children.
“It just feels so immediate,” says executive producer Nigel Marchant. “You’re completely thrown in with this premise—it’s any parent’s worst nightmare.”
How It All Begins
The story opens on a quiet afternoon in Chicago. Marissa arrives at Jenny Kaminski’s (Dakota Fanning) house to pick up her son Milo, only to find that no playdate was ever arranged. Jenny insists she never planned the visit, setting the mystery in motion.
Author’s Summary: The finale of All Her Fault transforms a simple abduction story into a haunting exploration of parental fear, buried guilt, and the devastating cost of uncovering the truth.
