Belfast, 21 July 1972: in the space of eighty minutes, the Provisional IRA detonates twenty-two bombs across the city, most of them car bombs driven to their targets that same afternoon. Nine people die, including two British soldiers, and 130 are injured. This BBC Northern Ireland production, made for the bombings' fortieth anniversary, reconstructs the day hour by hour, tracing how a campaign already running at a pace of over a thousand bombings that year escalated into an attack aimed simultaneously at economic, political, and military targets after talks between the IRA and the British government broke down. The film sets the carnage in Belfast's streets and shopping areas against the broader arc of the Troubles, showing how Bloody Friday became the direct justification for Operation Motorman, the British Army's move into IRA-held areas of Belfast and Derry just ten days later. It treats the day as a hinge point, the moment the conflict's methods and its consequences became impossible for either side to ignore.
