Colin Wallace started out as a young Ministry of Defence information officer in Northern Ireland and ended up running psychological operations during the Troubles, the sectarian conflict between Republicans seeking a united Ireland and Loyalists determined to stay part of the UK. The film traces how Wallace's job evolved from press liaison into manufacturing disinformation, planting fabricated stories, and shaping how the British public understood the violence in Belfast and Derry. It follows the paranoia and propaganda campaigns run out of Army press offices, and the murkier operations that blurred the line between countering terrorism and smearing political rivals. Wallace's own story turns strange when he is later convicted of a manslaughter he says was engineered to discredit him, a claim that becomes its own case study in the tactics he once deployed for the state. Interviews and archival material build a picture of a conflict fought as much through fake news and rumor as through gunfire, with Wallace himself as the case for how far a government psyops unit could reach.
