The film follows the fictional story of Henry Stanfield (Roger Allam), a career diplomat who has just been appointed as Truth Commissioner to Northern Ireland. But soon he learns the hard way that those in power will stop at nothing to suppress the truth about the violence of the past.
The Truth Commissioner is a taut, engaging drama in the style of those Sunday night BBC or ITV dramas that tell a story decently, but do not leave you clamouring for more.
