The dreams and utopias of a generation of men and women who dedicated their lives to the fight for justice, freedom, and democracy, using the story of Apolônio de Carvalho as a common thread. His fight, without frontiers, along with the Republicans in the Spanish Civil War, with the French Resistance against Nazism, and in the fight against the military dictatorship in Brazil in the 1960s.

In 1970, Brazil was in the throes of a military dictatorship that lasted 20 years. Persecutions, arrests, killings, kidnappings. The film Seventy rejoins 18 characters of this story, forty years later. The film mixes the excitement of revisiting the past with a vision, sometimes even good humored of everything they lived. Many years afterwards they relive their experience of pain, violence and survival, of rebuilding their own story and continuing to believe in the possibility of improving the world.
