About “All Her Fault” in a few words:

All Her Fault is a twisty mystery thriller miniseries that dropped on Peacock in November 2025. The story kicks off when Marissa Irvine goes to pick up her young son after a playdate — only to discover he’s gone and no one seems to know where he is. What follows is a tense scramble through lies, hidden agendas, and unexpected alliances as Marissa, her husband Peter, and their new friend Jenny dig deeper into the disappearance and unravel family secrets along the way.

Meet the characters from All Her Fault

Marissa Irvine

Marissa is the kind of main character who drags the whole story by the collar and refuses to let go — messy courage, a suitcase full of half-truths and receipts, you know? She’s stubbornly practical but also keeps weird little rituals (collects hotel keycards? hums 90s pop when stressed — don’t ask) that make her human, and sometimes maddening. Her decisions are what tip the scales in the plot; she carries guilt like a second coat and alternates between laser focus and absolute scatterbrained moments. She swears she’s calm and collected but you’ve definitely seen her pacing the kitchen at 2 a.m. with a glass of wine she insisted she never drinks.

Jenny Kaminski

Jenny is that loud, fiercely loyal friend who says the wrong thing at the right time and means it, always ready with an impractical plan and three snacks. She’s sharp, a little reckless, and has this uncanny ability to read a room — except when she totally misreads it and then apologizes with baked goods. Underneath the quips she’s dependable as hell; she deserts no one, though she will flip a table if provoked (not literally, maybe once). She swears she hates authority but once spent a summer doing volunteer paperwork because she couldn’t stand someone else doing it badly.

Detective Alcaras

Alcaras is the grizzled, relentless investigator who notices the loose thread you thought you’d hidden — the kind of cop who drinks awful coffee at dawn and keeps business cards in a shoebox for reasons that make sense only to him. He’s methodical, quiet, and haunted by an old case (you can tell because he avoids old recordings and names like a ghost), but he has a soft spot he absolutely refuses to admit. He’ll cross lines, not out of malice but because he genuinely believes the ends sometimes justify spent rules; also he collects matchboxes? Don’t ask me where that came from. He hates lies but also tells the occasional white one and then looks embarrassed about it for hours.

Peter Irvine

Peter wears the polished suit and the “devoted father” smile, but there’s definitely something buttoned-up and secretive going on beneath that tie — part patron, part strategist, part apologetic man who forgets anniversaries but remembers everyone’s middle name. He’s charmingly controlling in the way he rearranges a room to “make it efficient” and then insists it’s for comfort; he does charity speeches and also nags about the thermostat. He can be warm and genuinely protective, yet his decisions tend to ripple in ways he didn’t intend, which makes him a fascinating, slightly terrifying presence. He claims to be a decent cook (and to be fair, he can make one amazing stew) but will somehow burn toast.

Milo Irvine

Milo is the awkward, clever kid/adult-sorta-in-between who communicates mostly through playlists and eyebrow raises, that quiet storm who notices the tiniest detail and then disappears to sketch it or hack a file or whatever he does when deep in thought. He’s tender and defensive at the same time — loves animals (despite being allergic? maybe), hoards rubber ducks for reasons nobody understands, and is surprisingly brave when it counts. He can be infuriatingly cryptic about his feelings but will drop everything to help someone he cares about; also he says he hates parties but shows up with homemade cookies. He’s the screwball heart of the family and occasionally the source of the best plot twists.
