Oct. 10 (UPI) -- Sarah Snook and her family come under suspicion after her young son, Milo, goes missing from a playdate in a trailer released Friday for All Her Fault, a new mystery thriller series on Peacock.

Snook plays Marissa Irvine, a woman who arrives at a house to pick up her son from a playdate only to find that she doesn't know the woman who lives there and the woman doesn't have her son.

"As every parent's worst nightmare begins to unfold, new questions lead to deep secrets, revealing cracks in the Irvines' seemingly perfect world until everything is left shattered," a synopsis for the series reads.

Marissa's husband, Peter, is played by Jake Lacy, and Michael Peña is Detective McConville, who is investigating Milo's disappearance.

It soon becomes clear the Irvines and the people close to them are under suspicion by investigators.
