Oliver Stone is standing in Lafayette Park with his friend and fellow Camel Club member Harry Finn when a bomb detonates and knocks him unconscious. When Stone awakens in the hospital he learns that the British Prime Minister might have been target of the bomb blast. Only a last second change in plans saved the man's life.
There were three people in the park that night that shouldn't have been. Stone and Harry Finn are tasked to find out who they are and whether they had any ties to the bombing. The UK sends Mary Chapman, a lethal and experienced MI6 agent, to help Stone and Finn with the investigation. Stone senses that his government is willing to sacrifice him during this investigation and he must watch his back.
