James Nesbitt stars in this crime miniseries set in Northern Ireland. The discovery of an abandoned vehicle prompts DCI Tom Brannick (Nesbitt) to open an investigation. When the vehicle is traced back to Pat Keenan (Peter Ballance), Brannick is advised to delve no deeper for fear of his past connections with the IRA during The Troubles. However, Brannick has his own personal reasons for looking into the case as he attempts to heal old wounds.
