To prevent Iran from going nuclear, intelligence officer John Tavner must forgo all safety nets and assume a perilous "non-official cover" that of a mid-level employee at a Midwestern industrial piping firm.

In season 2, John must make a choice at the train platform - be free from his obligations and adversaries by letting Agathe take the money or pursue her, at great risk to himself, in an effort to protect his brother, father, and country. Meanwhile, his father presents a perilous way out of it all: find and assassinate Cantar Walley in Paris.
