Madam Secretary

CBS | 10:00 pm

Real-life former U.S. secretaries of state Hillary Clinton, Madeleine Albright and Gen. Colin Powell guest star as themselves in the Season 5 premiere, "E Pluribus Unum," which opens in the aftermath of a terrorist attack on the White House. As a manhunt for the assailants brings the nation’s capital to a standstill, Elizabeth (Tea Leoni) scrambles frantically to keep a critical nuclear disarmament deal from falling apart. Accordingly, she turns to some predecessors for their advice. Linda Lavin and Christine Ebersole also guest star.
