That means more Elizabeth ( Téa Leoni) and the return of Morgan Freeman as Chief Justice Wilbourne.
WATCH: Preview Of The Madam Secretary Season 4 Premiere
An all-new season of Madam Secretary premieres on Sunday, Oct. 8 at 10/9c on CBS and CBS All Access with an episode entitled "News Cycle," which follows what happens when a "fake news" story surfaces that claims Elizabeth is responsible for a diplomat's death after he suddenly dies in their private meeting.
But, before you settle in to watch, know that there will be a few changes!
Madam Secretary has been pushed one hour later to the 10/9c slot on Sunday nights.
However, fans may still want to pull up a chair at 9/8c to enjoy NCIS: Los Angeles, which is heading into its ninth season.
