Based on a true story, this gripping thriller plunges viewers into the violent world of the Northern Ireland conflict. Jim Sturgess stars as Martin McGartland, a young Catholic man recruited by a British intelligence agent, played with chilling intensity by Ben Kingsley, to become an informant within the Irish Republican Army. Forced to lead a double life, Martin must earn the trust of hardened IRA members while secretly feeding information to his handler that could save countless lives. As he becomes more deeply embedded, the line between his loyalties blurs, and he finds himself in constant fear of discovery. The tension is palpable as Martin walks a razor's edge, knowing that a single misstep could lead to his brutal execution, a fate that has befallen the "fifty dead men" before him. Directed by Kari Skogland, this action-packed drama is a relentless exploration of survival, loyalty, and the impossible choices made in the name of peace.
