It is one of the ill-kept secrets of America's intelligence agencies--for decades, they have worked virtually non-stop to perfect means of controlling the human mind. But while many have suspected the existence of these projects, the details have long been preserved. This program examines these experiments, drawing on documents reluctantly released through the Freedom of Information Act and interviews with some of the victims, including a woman whose past was literally taken away. Hear from John Marks, the author of In Search of the Manchurian Candidate, who broke the story of the CIA's abuses by unraveling the mysteries contained in financial records. All the other records pertaining to the experiments were destroyed by the agency in an attempt to prevent the details from ever being known.
