In 1992, twenty-eight families came together in the pursuit of truth and justice. Eighteen years later, they moved a mountain. Setting the Truth Free captures, for the first time, the remarkable story of the Bloody Sunday families of Derry. The wounds of Bloody Sunday cut deep and have spanned generations; decades after the atrocity, a group of determined strangers - united in grief and anger - met and mobilised themselves to campaign for a new investigation into the killings and the exoneration of the victims. Establishing the Bloody Sunday Justice Campaign, they embarked upon one of the most remarkable human rights movements in history. To the end, it was a struggle - meeting with scorn and obstruction by fellow citizens, the Bloody Sunday families persevered. Writing to politicians, newspapers and anyone who would listen; fundraising, lobbying from Westminster to the White House and Capitol Hill and canvassing thousands door-to-door, their remarkable global campaign led to the establishment of the most complex and expensive Inquiry in British legal history. After twelve years, Lord Saville's report found that the British army's actions on Bloody Sunday were both 'unjustified' and 'unjustifiable' and made headline news all over the world. Now, forty years after that tragic day, and with the universal declarations of innocence still ringing in their ears, those most affected by Bloody Sunday have their say. This is the inspirational story of how a group of ordinary people stood up to the might of the establishment - and won.
