Carrie Mathison (Claire Danes) was last seen adding a star to a memorial at Langley to honor Brody (Damien Lewis). She was pregnant at the time with Brody's child and appears to have given birth to a little girl.
Mathison was planning to take a new job as a CIA station chief in Istanbul. However, the promo places her in Pakistan.
She is there dealing with explosions, riots, and attacks.
Saul (Mandy Patinkin) is working with her. Peter Quinn (Rupert Friend) and Dar Adal (F. Murray Abraham) are also back.
However, during Homeland's panel at the 2014 Television Critics Association press tour, it was confirmed that Dana Brody (Morgan Saylor) will not be returning.
