Kate, for her part, makes it clear that she is not trying to end her marriage to Hal. Instead, she wants to find a way to reconnect with him, even though their differences are likely to lead to increasingly heated confrontations.
The conflict extends far beyond their romantic relationships. A catastrophic event threatens the fragile peace Kate managed to establish between the United States and the United Kingdom. As she tries to contain the fallout, the ambassador must confront a conspiracy involving Grace, Hal, and one of Russia’s most powerful weapons.
The goal will be to prevent that alliance from triggering an international escalation that could draw the United States into war. Kate and Todd will have to work together to contain the fallout from Grace and Hal’s actions and preserve the balance of power.
