In 2003, Maya, a young U.S. Central Intelligence Agency officer, has spent her entire brief career, since graduating from college and being recruited for the agency, focused solely on gathering intelligence related to Osama bin Laden, leader of al-Qaeda, following the terrorist organization's attack on the United States in 2001. She is reassigned to the U.S. embassy in Pakistan to work with a fellow officer, Dan. During the first months of her assignment, Maya often accompanies Dan to a black site for his continuing interrogation of Ammar al-Baluchi, a detainee with suspected links to several of the hijackers in the September 11 attacks. Dan subjects the detainee to approved interrogation techniques, i.e., stress positions, hooding, subjection to deafening noise, sleep deprivation, waterboarding, and humiliation. After failing to get al-Baluchi to give up information on an attack in Saudi Arabia, he and Maya eventually trick Ammar into divulging that an old acquaintance, who is using the alias Abu Ahmed al-Kuwaiti, is working as a personal courier for bin Laden. Other detainees corroborate this, with some claiming Abu Ahmed delivers messages between bin Laden and a man known as Abu Faraj al-Libbi. In 2005, Abu Faraj is apprehended by the CIA and local police in Pakistan. Maya is allowed to interrogate him, but he continues to deny knowing a courier with such a name. Maya interprets this as an attempt by Faraj to conceal the importance of Abu Ahmed.
