The Oath tells the story of Abu Jandal, Osama bin Laden’s former bodyguard and Salim Hamdan, a prisoner at Guantanamo Bay prison and the first man to face the controversial military commissions. We meet Abu Jandal as he transports passengers through the chaotic streets of Yemen’s capital city, Sana’a. Salim Hamdan is the film’s "ghost” protagonist. His seven-year captivity at Guantanamo is narrated through his prison letters. Following the story of these two men, The Oath takes the viewer on a journey that leads to Afghanistan, Osama bin Laden, Guantanamo Bay Prison, FBI interrogations and the US Supreme Court.
