Northern Ireland's loyalist paramilitaries get the same scrutiny Peter Taylor already gave the IRA, tracing how working-class Protestant estates in Belfast and Derry produced the Ulster Volunteer Force and the Ulster Defence Association. Taylor interviews former gunmen and commanders alongside British army and intelligence officers, letting both sides describe the bombings, assassinations, and internal feuds that defined three decades of violence. The series does not treat loyalists as a simple mirror of republicanism: it follows the UVF's origins in 1966 and the UDA's later mass membership, and it presses hard on allegations that British security forces passed intelligence to loyalist killers, sometimes naming targets. Victims' families appear on camera describing specific attacks, giving the political history a personal cost that the interviews with paramilitary leaders alone would not carry. Taylor keeps his own presence minimal, letting participants make their case and contradict each other, so the collusion question stays open rather than resolved by narration. It closes with the movement's uneasy accommodation to the peace process.
