CIA analyst Charlie Tucker and President Payton consider how to avenge the death of Payton's son, who was killed a year ago in Kabul when a diplomatic convoy was attacked.
A stranded Russian submarine contains stolen US secrets, Charlie receives an incriminating picture, and President Payton selects a new CIA director.
Charlie recalls the first time she met Nick, members of a militant Islamist movement capture 21 Nigerian girls, and the Chinese President comes to Camp David.
After Charlie and Nick get a threatening text, Nick embarks on an investigation to find the source. Also, information from a rival causes the President to question Charlie's faithfulness, while Jack Dawkins must contain a smallpox contamination.
President Payton has questions for Nick Vera after part of the convoy-attack report is leaked, while Kurt works up the courage to show Maureen his hand.
During a trip to Qatar with the president, Charlie deals with a local who claims to be a CIA asset; however, the agency has no record of the man. Also, Charlie takes a deadly risk in pursuit of the truth about her fiance's death.
