The film deals with the judgment of the so-called "compromised", who integrated the colonial apparatus. At Josina Machel school, in an amphitheater with a full audience and balcony, there is a stage where Samora Machel and the members of the Frelimo political committee are located. He records Samora, an impeccable political actor, sometimes histrionic, in the role that he is attributed as the animator of the scene in the trial.
The agitprop film Estas são as armas by Murilo Salles was edited together from archival images and formed one of the first works to be produced by the newly founded film institute in Maputo.
It is the first film produced at the extinct ICA (Instituto Central de Artes), in a co-production between UnB (Universidade de Brasília) and the also extinct INC (Instituto Nacional de Cinema). Held at the Festa do Culto ao Mito do Divino Espírito Santo in Pirenópolis, state of Goiás, in 1968, it was completed in 1969, in Rio de Janeiro. The film is extremely important for the memory of Brazilian popular culture and the state of Goiás, as it is a work of art about this popular festival, and not just a documentary record, as it reflects its cultural character. Today the party is considered Cultural Heritage of Brazil by IPHAN.
