Writer-director Paul Greengrass' drama is a re-creation of the events of Sunday, January 30th, 1972, when British troops clashed with unarmed protestors in Derry, Northern Ireland.

In documentary style, Paul Greengrass' BLOODY SUNDAY, which chronicles the events of January 30, 1972 in Derry, Ireland, is filmed with gritty gray realness. Surrounding a peaceful protest march staged in contest to British laws that permitted internment without trial, the film charts the progress of the march from the night before it to the night following it. As the final organizing of the march takes place that morning, MP Ivan Cooper (James Nesbitt) rushes from the street where police barriers are being erected to his office where he fields a string of urgent phone calls. Meanwhile Major General Ford (Tim Pigott-Smith) arranges for a heavily armed troop of commandos in fatigues and face paint to be ready to intercept the march if it turns violent. A third persona, Kevin McCorry (Allan Gildea), is a young lad with a prison record who believes in the cause of the march but wants to avoid conflict and any real trouble. As the march proceeds, and chaos ensues, the British militia opens fire onto the unarmed crowds, shooting 27 and killing 13 in one of the most shocking instances of excessive force in Irish history, ending any hope of nonviolent resolution, and stoking the IRA.
