Kate is a rising star in one of London's top barristers' chambers. Smart, competitive and driven, she is jubilant when she lands a high-profile case representing the TV talent show judge, Jez Carnaby. Children are involved, as are houses, helicopters, racehorses, private islands, and money - lots of it. Winning this case will guarantee Kate the success and stability she craves. There's only one problem: on the opposing legal team is her own husband, Rikki. Frost settles on their previously hot marriage. Kate is outraged by Rikki's sympathy for his female client, whom Kate sees as a negligent mother and freeloader. Rikki is disgusted that contact with Carnaby is making her as selfish as her client. Suddenly issues which they could laugh off or resolve in bed erupt into quarrels, whether about who puts out the rubbish bin or about Kate's ambivalence towards having children. Fighting the case in the court by day while sharing a bed by night, both must reassess their ideas about parenthood, fidelity and the equality of men and women in a modern marriage.
