The narrative is set against the backdrop of the motion picture industry, exploring the complexities of fame, relationships, and the darker side of the glamorous world of film. At the start of the novel, Kennedy is called to the scene of the tragedy in a luxurious library where Stella has collapsed while filming a scene.
