Madrid, Spain, February 23, 1981. A group of Civil Guards storm into the Congress of Deputies and terrorize those present by firing shots into the air. Only three men remain unmoved: Prime Minister Adolfo Suárez; Vice President Manuel Gutiérrez Mellado; and Santiago Carrillo, leader of the Communist Party.

It tells the story - inspired by the novel of the same name, published in 2018 by the Alicante writer Elia Barceló - of a group of women whose stable, successful lives are suddenly shattered as the human remains are found of one of their high school classmates, who disappeared during their end-of-year trip to Mallorca twenty years ago.
