Thousands of people are in jail in dozens of countries because they hold religious and political beliefs, opinions or ideas not approved of by the ' authorities '. The imprisonment of these ' prisoners of conscience' is in violation of the United Nations Declaration of Human Rights. This film tells the story of two men, Gustavo Westerkamp , held in Argentina for five years without trial, and Danylo Shumuk , who has been in jail in the USSR for over 35 years. It also shows the work of people fighting for the release of these two - and of the thousands of other individuals and groups who, under the umbrella of Amnesty International, which this year celebrates its 20th anniversary, devote their spare time to working for the freedom of people they have never met. Written and presented by Vanya Kewley
