The series All Her Fault begins as a gripping mystery about the disappearance of Milo Irvine, the young son of Marissa (Sarah Snook) and Peter Irvine (Jake Lacy). What starts as a straightforward kidnapping case soon unfolds into a disturbing story filled with hidden motives and deadly secrets.
Marissa arranged a playdate for her son with Jacob, the child of her acquaintance Jenny (Dakota Fanning). When she arrived at the address Jenny had given her, she discovered it wasn’t Jenny’s home—and Milo was missing. A teacher later confirmed that Milo had been picked up from school by Carrie Finch (Sophia Lillis), the nanny of Jacob.
While Carrie’s identity as the kidnapper was revealed early in the series, her reasons turned out to be far more twisted than anyone could imagine. The show delves deeply into her dark past and the emotional triggers that led her to commit the crime.
“All Her Fault isn’t just a whodunit—it’s a story about how buried secrets can destroy lives when they finally come to light.”
The show takes inspiration from Andrea Mara’s novel of the same name but ventures beyond the original story. It keeps the core premise intact yet adds a darker, psychological edge, layering betrayal and trauma into every revelation.
Author’s Summary: A psychological thriller where a simple kidnapping unravels into a haunting web of secrets, lies, and moral corruption.
