On November the 4th 1969, Carlos Marighella is caught in an ambush and killed by the bullets of 80 policemen armed with revolvers and machine guns. He was considered public enemy number 1 by the Brazilian military dictatorship, which believed that it could quell the urban guerilla movement by liquidating him. This movie, made after his death, reconstructs, through interviews with road companions and friends, the life and political struggle of Carlos Marighella.
