A young man leads a perilous double life when he becomes an undercover informant within the ranks of the IRA.
Belfast in the 1980s, with no end in sight to the decades-long conflict of the 'Troubles'. A fearless 22-year-old hustler, Martin (Jim Sturgess) feels little empathy for the Irish Republican Army (IRA) and the violent brand of justice they wield in the city's estates.
But Martin has attracted the attention of Fergus (Ben Kingsley), master of surveillance and an experienced 'handler' with British intelligence.
Fergus plans to use Martin as an informant, infiltrating the IRA and then reporting on their activities from the inside.
While working his way through the IRA's ranks and fighting to keep his identity secret, Martin must also protect his girlfriend Lara (Natalie Press) from the deadly reality of his situation.
But the IRA are onto him, and Martin finds himself in the hands of their most feared torturer...
