On the night of the State Dinner honoring the Prime Minister of England, Oliver Stone is across from the White House in Lafayette Square. As the Prime Minister's motorcade drives by there is an explosion: a bomb has been detonated, in what looks like a terrorist plot directed at the President and the Prime Minister. In the aftermath, British MI-5 agent Mary Chapman, an experienced, lethal operative with an agenda of her own, is sent to assist and coordinate with American authorities to uncover who was responsible for the bombing. Stone, together with Harry Finn and the rest of the Camel Club, are drawn into the investigation. But everything is not what it appears to be. It seems that the mysterious attackers might have another target in their sights, and if the Camel Club is unable to stop them, the results would be nothing less than catastrophic.
