Season four of MADAM SECRETARY finds Elizabeth (Téa Leoni) trying to achieve diplomacy despite many global enemies poised against her and new political rivals at home. Henry (Tim Daly) takes on a new role at the CIA, which sometimes puts him at cross-purposes with Elizabeth, both professionally and personally. Also this season, their daughters Stevie (Wallis Currie-Wood) continues with her internship in Russell Jackson's (Željko Ivanek) office and Alison (Kathrine Herzer) goes off to college, press secretary Daisy (Patina Miller) has a baby, and the president's chief of staff Dmitri (Chris Petrovski) returns.
