As tensions rise with Russia, Elizabeth, Russell and Mike B. hatch a plan to oust National Security Advisor Craig Sterling without tarnishing President Dalton with a scandal. Director of National Intelligence Ephraim Ware identifies who hacked Air Force One.

Shortly before Elizabeth is to deliver a speech at the United Nations accusing Russia for the attack on Air Force One, Henry shares information that makes her reconsider her theory.

After they uncover a secret that could ruin Maria Ostrov’s reputation, Elizabeth and President Dalton head to Switzerland to meet with her and use the information as leverage to find a peaceful solution to the escalated conflict with Russia. Also, Dmitri requests to be released from his duties as a spy.

Following a shocking event on U.S. soil, Elizabeth rushes to find answers to President Dalton's many questions about how it was able to occur.

After U.S. environmental activists protesting China’s damage of a South China Sea reef are arrested for spying, Elizabeth finds herself in a stalemate with the Chinese foreign minister as she lobbies for their release.

When a possible Israel-Iran war threatens the House’s imminent vote on the U.S. presidential election, Elizabeth attempts to bring the two reluctant countries to the negotiation table in an effort to broker a peace between them. Also, Russell’s life hangs in the balance after a heart attack.

When a computer sting uncovers the possible mole in the CIA arms smuggling ring, Elizabeth’s questioning of the suspect makes her think that a larger, more dangerous force is behind the operation. Also, Henry worries that the doomsday cult is drugging his embedded operative, and Elizabeth and her State Department staff come up with an unorthodox approach to solving black rhino poaching in Namibia.
