The authoritative journalist Fulvio Grimaldi - the only Italian photojournalist to document the peaceful March for civil rights of 30 January 1972, in Derry, culminating in the massacre sadly known as Bloody Sunday - returns to Northern Ireland, forty-five years later, to testify to the third investigation on Bloody Sunday. Once in Derry, he discovers that on the outer walls of the houses of the Bogside - the most important Catholic neighborhood in the city - murals are painted that tell the most significant events of recent Northern Irish history. Fascinated by the communicative power of the works, one of which inspired by one of his photographs that became an icon of Blood Sunday, Fulvio came into contact with the Bogside Artists, the authors of the murals, and with the people who were involved in the painted events. A journey between past and present steeped in art, history and deep emotions; the encounters, memories and testimonies determine a dramatic immersion in the reality of that place and tell its story: Bogside Story.
