Persons of Interest is a four part series where former activists and political dissidents are given their previously secret ASIO files and asked to explain the allegations contained in them. As a result, the series unravels the hidden political and cultural history of Australia that is still being unmasked today in a world gripped by confirmations of mass surveillance abuses by ASIO and other intelligence agencies such as the NSA in the United States. Using the content of the ASIO records themselves along with genuine surveillance footage, this series tells the story of spies, traitors and intelligence intrigue in Australia against a backdrop of the big political events of the 20th century; at a time when fear of Communism, outsiders and threats to the established order fostered the construction of a vast and secret network of surveillance on ordinary people.
