A suspicious homicide at an elementary-school fundraiser in Monterey, CA raises eyebrows that the crime was related to rivalries and secrets among three mothers.
Madeline is a stay-at-home mom who harbors jealousy towards her ex's new wife. Madeline's best friend Celeste is a former lawyer with an outwardly-perfect marriage to a younger man. And Jane is a single mother with a dark past who is taken under Madeline and Celeste's wing.
The school's staff and other parents share their opinions on the town's allegiances and rivalries, with a focus on Madeline and a tech-executive rival of hers, Renata.
As more of the story is revealed, it comes to light how each of the women had something to hide leading up to that one fateful night.
Based on the bestselling novel of the same name.
