Carrie arrives in Islamabad as the new station chief and learns that it has been placed on lockdown under Martha's orders. However, Carrie has set up an alternate base of operations with Fara and Max, aiming to establish contact with Aayan (who has been threatened out of talking to the media). After Aayan refuses to speak with Fara, Carrie makes contact herself, posing as a journalist, and offers Aayan protection as well as safe passage to London where he can continue his medical studies.

Aayan discovers that he has been expelled from his university for stealing medicine samples. With nowhere else to go, he accepts Carrie's offer.

Carrie interviews Aayan about his relationship with Haqqani, his uncle, but he panics when she broaches the rumor that Haqqani may be alive.

Carrie gives Aayan his new passport and rehearses him on the details of his identity. He and Carrie are attacked by several men at the safehouse, but Aayan is able to escape. The break-in is revealed to be a ruse engineered by Carrie to prompt Aayan to seek refuge with his uncle, Haqqani.

Quinn learns that Ghazi never left Isl

Over live video, Haqqani presents a captured Saul to the U.S. embassy and names the prisoners he wants released, but Saul begs the U.S. to refuse Haqqani's demands. That night, Saul escapes his captivity, and i
Carrie has Dennis detained at the embassy with Martha's help. During the prisoner exchange, the Taliban use a young boy wearing a suicide vest as leverage to ensure the release of the five prisoners.

Dar Adal informs Saul that he made a deal with Haqqani, who agreed not to harbor terrorists in Afghanistan in exchange for being removed from the CIA's kill list.
