'Ms. Sandberg was right about something. We had to lean in. It was the only way to hear the whispers...'

Sloane, Ardie, Grace and Rosalita have worked in the same legal office for years. The sudden death of the firm's CEO means their boss, Ames, will likely take over the entire company. Each of the women has a different relationship with Ames, who has always been surrounded by whispers about how he treats women. Those whispers have been ignored, swept under the rug, hidden away by those in charge.

But the world has changed, and the women are watching this latest promotion for Ames differently. 

This time, they've decided enough is enough.

Sloane and her colleagues' decision to take a stand sets in motion something catastrophic and unstoppable: lies will be uncovered, secrets will be exposed and not everyone will survive. All their lives - as women, colleagues, mothers, adversaries - will be changed for ever.
