Sergeant Lindsay Boxer, Medical Examiner Claire Washburn, Assistant District Attorney Yuki Castellano, and crime writer Cindy Thomas are celebrating at San Francisco's finest restaurant. But before they can raise their glasses to both a birthday and a wedding, a violent assault interrupts their festivities. Claire examines the victim. Lindsay makes an arrest. Yuki takes the case. Cindy covers it. The case is complicated by the plaintiff's unreliable version of events - and the shocking reason behind her ever-changing memory. As Yuki argues the toughest case of her career, Lindsay chases down a high-society killer whose target practice may leave the Women's Murder Club short a bridesmaid . . . or two.
