Amid the civil-military dictatorship established by the coup of 1964, Sergio Muniz had the idea of mak...展开ing a documentary about the action of Esquadrao of Death. At the time, to the documentary, the press still had some freedom to disseminate the action of these groups of extermination, trained by police from many different levels, and that acted in the suburbs of cities like Sao Paulo and Rio de Janeiro. The victims of police repression (as now) were men, poor and black, and for this condition, supposedly criminals. Years later, in 1974, after a long period of production in Europe and Cuba, the film is ready. Meanwhile, following the advice of friends in Havana, chooses not to show the film. "They told me they found better not display it in Brazil: 'you can endanger not only you but also the actors appearing in the film', they said. From the positive impact, began to make an informal and free distribution of copies of the documentary.
