Peacock has released a trailer for its drama series All Her Fault, which lays out what will be a very rough time for the shows lead character.

Succession Emmy winner Sarah Snook stars in the series as Marissa Irvine, who arrives to pick her son, Milo (Duke McCloud)m], up from a playdate and discovers that (per the shows logline) the woman who answers the door isnt a mother she recognizes. She doesnt have Milo and has never heard of him. As every parents worst nightmare begins to unfold, new questions lead to deep secrets, revealing cracks in the Irvines seemingly perfect world until everything is left shattered. As the detective (Michael Pea) investigating the case says late in the trailer, I honestly didnt see this coming these nice people, killing each other. Watch the trailer below.

Based on a best-selling novel by Andrea Mara, the Chicago-set All Her Fault is Snooks first series since Succession ended in 2023. Jake Lacy, Dakota Fanning, Pea, Sophia Lillis, Abby Elliott, Daniel Monks, Jay Ellis, Thomas Cocquerel, McCloud and Kartiah Vergara also star; Johnny Carr, Linda Cooper and Melanie Vallejo have recurring roles.

All Her Fault comes from Universal International Studios. Megan Gallagher (the BBCs Wolf, Apple TV+s Suspicion) adapted the novel and executive produces with Nigel Marchant, Gareth Neame and Joanna Strevens of Carnival Films, Snook, Minkie Spiro, Christine Sacani and Jennifer Gabler Rawlings. Terry Gould produces, and author Mara is an associate producer.

Spiro (3 Body Problem, Pieces of Her) directed the first half of the eight-episode season, and Kate Dennis (The Handmaids Tale, GLOW) helmed the second half. The series is set to premiere Nov. 6.
