Seven days in May: David Riondino, an Italian film director, is coming to Spain to document the Atocha massacre of 1977, to make a film on its 50th anniversary. He will be helped by Alejandra, a young documentary filmmaker who urges him to contextualise the past with the current rise of the far right. By investigating the Atocha attack, David will recover a part of that recent past and at the same time will witness a reality that encourages reflection on some burning issues such as the advance of the far right, problems of access to housing and job insecurity.
