Bloody Sunday plot
Sunday 30 January 1972, Derry, Northern Ireland. Ivan Cooper is organizing a nonviolent march for equal rights between Catholics and Protestants. He is determined to rule out all violence between the various parties. But despite his consultations with the Unionist authorities and his attempts to negotiate with British security forces, the demonstration spirals out of control: 13 people are shot dead by the army. Since that day, January 30 has been known as "Bloody Sunday". A date that also marked the start of the civil war in Northern Ireland.
