Thriller loosely based on the autobiography by Martin McGartland, former undercover informant to the British police on the activities of the IRA. Set in Belfast in the late 1980s, the film shows how McGartland led a double life for four years while still in his early twenties, revealing nothing of his position even to close friends and family, until his cover was blown in 1991 and he was kidnapped and tortured by the IRA. Ben Kingsley co-stars as Fergus, McGartland's British 'handler'.
