John Tavner is a former intelligence officer who leads a complicated life. Deciding to return to duty, his latest assignment tasks him with forgoing all safety precautions in a "non-official cover" role as a mid-level employee at an industrial piping firm in the Midwest in order to prevent Iran from obtaining nuclear capabilities.
Jeopardizing this already-perilous mission is the necessity of holding his cover day job while dealing with his own PTSD and the incompetence of the federal government.
