In 2009, the CIA officers in Afghanistan's Kabul Station received information regarding the whereabouts of Osama bin Laden. But when they followed the informant they discovered it was a deadly trap. The man blew himself up, taking the chief of station and several senior officers with him. Two years later, the station still hasn't recovered. Every initiative meets with failure and no one knows who to trust. John Wells' reluctantly goes over to investigate, but what he finds when he gets there is more than a station in disarray. Americans are dying, and an American is responsible - and that's just the beginning.
