On 22nd April 1993, 18-year-old black student, Stephen Lawrence was murdered in a racist attack. Thirteen years later, in 2006, Stephen's family are still fighting for justice. DCI Clive Driscoll finds Stephen's cold case files. He is convinced that the crime can be solved but his interest in the case attracts hostility from colleagues. After a series of forensic breakthroughs, two of Stephen's suspected killers, Dobson and Norris, are arrested and stand trial. While they await the verdict, Doreen Lawrence tells Clive that whatever the outcome, the fight for justice will go on.
