A professional ghostwriter is hired to complete the memoirs of Adam Lang, a former British Prime Minister embroiled in controversy. The original writer's death under mysterious circumstances casts a shadow over the project. The ghostwriter takes up residence at Lang's isolated beachfront mansion in the United States to work on the book. As he delves into his predecessor’s materials and interviews with Lang and his associates, the writer discovers secrets that put the subjects of his book—in particular, Lang's political decisions and personal life—under a new, more dubious light.

Amidst his research, the ghostwriter uncovers inconsistencies and confidential information that suggest the former Prime Minister's past may have a darker and more complex history than the public persona portrayed. His investigation attracts attention, leading to an unsettling atmosphere where the writer's every move is scrutinized. As tension builds, the writer finds himself entangled in a web of political and personal intrigue, with the stakes rising far beyond the scope of a mere biography. He must then navigate a treacherous path marked by potential danger and ethical dilemmas, where each revelation ups the ante of the narrative he has been tasked to tell.
