Based on the writings of Jorge de Sena, the iconic caricatures of João Abel Manta about the Salazar years, and the music of Zeca Afonso, a team of creatives from the animation studio Filmógrafo (Abi Feijó, Clídio Nóbio, Manuel Tentúgal, Márcia Luças, Luísa Leal, Tita Costa, Tito Morais and Riu Braz) created a panoramic film about the history of Portugal during the 20th century: From the Colonial War, fascist propaganda, capitalism, clericalism, the repression of the PIDE, to the hopes of the April revolution.
