 In 1998 former Chilean dictator Augusto Pinochet visits Britain for medical treatment. On being tipped off, Amnesty International seize the chance to bring to justice a man they insist is guilty of multiple human rights violations. The newly-elected Labour government is initially amenable, and soon Pinochet is under house arrest (albeit in a detached house in leafy suburbia) and awaiting extradition to Spain. However, Amnesty are up against the complexities of British law, the vacillations of Home Secretary Jack Straw, Pinochet s former ally Margaret Thatcher - and the Senator s own vast reserves of cunning.
