HOMELAND is an edge-of-your-seat sensation. CIA officer Carrie Mathison is volatile and unpredictable. With the help of her mentor Saul Berenson, she fearlessly risks everything, including her sanity, at every turn.

The first season of the American television drama series Homeland premiered on October 2, 2011 on Showtime, consisting of 12 episodes. The series is loosely based on the Israeli television series Hatufim (English: Prisoners of War).
