Wife, mother, and diplomat Elizabeth McCord (Tea Leoni) is used to solving the most desperate crises overseas, but this time, the danger is closer than ever. As global tensions continue to mount, the McCord family becomes the focus in a sinister stalking case, the culprit of which no one could ever suspect. If a personal target wasn't enough, Elizabeth's husband Henry (Tim Daly) is assigned to take down a violent doomsday cult that is preparing to strike. Meanwhile, Elizabeth uses her sage counsel to ensure President Conrad Dalton's (Keith Carradine) re-election, all while White House Chief of Staff Russell Jackson (Zeljko Ivanek) provides difficult demands of his own. She may be savvy in all corners of the world, but with the help of Nadine Tolliver (Bebe Neuwirth) and her brilliant team, Elizabeth is next to unstoppable.

In season three of Madam Secretary, it's not politics. It's personal.
