Having been convicted of Una Lynskey's murder, Martin Conmey and Dick Donnelly began their sentences in Mountjoy prison in 1972.
For Martin, his release almost three years later was supposed to mean a return to normality and a fresh start, but he found it almost unbearably hard to live with everything that had happened.
However more than a decade later, one seminal moment in the history of The Troubles would ignite a determination in Martin to challenge the might of the State once more.
It would take a change in the law, the unyielding love of his family, and yet more battles in the courtroom, but Martin set out to try get his conviction quashed.
