An interview of Luis Mattini, general secretary of the Workers' Revolutionary Party (PRT), and Enrique Gorriaran Merlo, member of the political bureau of PRT and commander of the People's Revolutionary Army (ERP), is the basis of this short documentary completed in Rome in 1978. Archive images accompany the voices of the guerrilla militants who denounce the crimes perpetrated by the Videla dictatorship and they present an overview of militant and political organization against the forces of imperialism.
