Meet Ava: rule-abiding lawyer who has ticked all of life's boxes. She's married to a successful surgeon and has just taken an indefinite career break to raise her adorable toddler. A picture-perfect life. Meet Winnie: Ava's old college roommate. Once awkward, quiet and apparently academically challenged, she left Stanford in a shroud of scandal. But now, she is charismatic, wealthy and has returned to town dripping in designer accessories. An actual perfect life. When the two women bump into one another at a local coffee shop, it seems like fate has intervened: Winnie's new-found success is courtesy of a shady business and she needs a favour; Ava is realising she is not built for the stay-at-home life. But what starts as one favour turns into two, then three, and soon Ava is in far deeper than she ever imagined. Now Ava has to make the ultimate decision: cut and run, or risk it all?
