On 21 November 1974, two bombs tear through the Mulberry Bush pub and the Tavern in the Town in Birmingham within minutes of each other, killing twenty-one people. Hugh Callaghan, Patrick Hill, Gerard Hunter, Richard McIlkenny, William Power and John Walker are convicted the following year and sentenced to life, largely on the strength of confessions and forensic tests later shown to be worthless. This Granada production lets the six men tell that story in their own words: the interrogations, the sixteen years inside, and the March 1991 Court of Appeal ruling that finally quashed their convictions. Human-rights lawyer Gareth Peirce, who worked to free them and the Guildford Four before them, appears to place the case in a wider pattern of miscarriages of justice built on manufactured evidence and political pressure to secure a conviction fast. The film treats the men's release not as an ending but as an indictment of the police and forensic work that put them away for a crime they did not commit.
