From 1970 onwards, and for two and a half years, the Revolutionary Brigades devoted themselves to armed struggle against the Portuguese dictatorial regime, as part of the fight against capitalism, colonialism and imperialism. They carried out dozens of actions, most of which were related to the colonial war, and were the only armed struggle organisation still active on April 25, 1974.  This documentary evokes the period from the establishment of the dictatorship in Portugal (1926) to the emergence of the Brigades, and then traces the unique history of this anti-fascist organisation and its actors.
