Derek Jacobi takes the lead in this powerful drama charting General Pinochet's enforced exile under house arrest in the UK from October 1998 to spring 2000. As Amnesty International and Chilean exiles campaign tirelessly to see the former dictator face trial for atrocities under his regime, old ally Lady Thatcher (Anna Massey) comes out of retirement to lobby for his release. Will Home Secretary Jack Straw be forced into making an embarrassing U-turn?
