Homeland season 8 will premiere in 2019 and will be the final season for Carrie Mathison, as planned by the showrunners. Homeland originally premiered in 2011 and introduced audiences to Mathison, a Central Intelligence Agency operations officer, who uncovers the plot of Nicholas Brody, a U.S. Marine Sergeant, who has been "turned" by al-Qaeda commander, Abu Nazir.

As the series progressed, Mathison leaves the CIA and goes on a variety of adventures that bring her to the Middle East and Europe. Season 6 brought her back home to the United States, where she finds work at a foundation that provides aid to American Muslims. During this time, the first female president of the United States is elected, Elizabeth Keane. After her election, an assassination attempt is carried out on Keane. The plot lays the foundation for season 7, which has Mathison taking on Keane, who has started an "America First" policy leading to the arrest of 200 members of the intelligence community.
