The film follows the story of Abu Zubaydah, the first high-value detainee subjected to the CIA's program, of Enhanced Interrogation Techniques (EITs), later identified as torture by those outside the agency.

Twenty years on, The Forever Prisoner reveals the origins of the clandestine operations that led the United States, in the 'War on Terror,' on a path of cruelty, deceit, and self-deception.
