A divorcing woman discovers the sordid truth beneath her glitzy life when she takes on her cheating husband and the tax haven island hiding his secrets.

On the paradise island of Jersey, society hostess and amateur aviator, Cass Hartmann, has a perfect life. A beachside home, a chalet in the alps, two gorgeous daughters and a to-die-for husband. She has everything, in fact, except for the truth.

At a lavish party hosted by a Russian oligarch, Cass discovers her husband, Magnus, has been leading a double life. She files for divorce and starts unravelling his clandestine business affairs, dreaming of a new life with half the marital spoils. Magnus cuts off her funds, alienates her from friends and family and absconds with their daughters. Alone, destitute, and with mysterious forces on the island working against her, Cass must find the strength within her. She joins forces with three women she meets in a relationship therapy group to delve into the murky corporate world to uncover an operation of money laundering, sanctions busting and arms dealing. When Cass is offered a vast out of court settlement to keep quiet, she is set on an unexpected path…
