Dr Francesca Stavrakopoulou asks whether the ancient Israelites believed in one God as the Bible claims. She puts the Bible text under the microscope, examining what the original Hebrew said, and explores archaeological sites in Syria and the Sinai which are shedding new light on the beliefs of the people of the Bible.

Investigative journalist Jeremy Scahill travels to Afghanistan, Yemen, Somalia, and other countries where the United States has taken military action in the War on Terror. In Afghanistan, he investigates the United States military and government cover-up of the deaths of five civilians, including two pregnant women killed by US soldiers from the Joint Special Operations Command. After investigating the attack, Scahill travels to other sites of JSOC intervention, interviewing both proponents and opponents, and the survivors, of such raids,including U.S. Senator Ron Wyden. Scahill also investigates the assassinations of American citizens Anwar al-Awlaki and his son Abdulrahman al-Awlaki, meeting with their family at their home in Yemen. Scahill suggests that the War on Terror is in fact a "self-fulfilling prophecy" and causes the radicalization of Muslims. He also discusses the case of Yemeni investigative journalist Abdulelah Haider Shaye who was detained, tried and sentenced on terrorism-related charges after reporting on American drone strikes.

When the official recovery operation is called off by the Norwegian and British authorities after being deemed too risky, the friends set out on a secret mission to retrieve the bodies themselves.
