Every event is a piece that together with the other parts tells the history of narcoterrorism in Colombia in the last three decades of the 20th century. How it was born, how it grew and how it extended throughout the country, how it permeated all social and political institutions, the violence it generated, the victims it left and the challenges it posed to the state, to the large economic conglomerates and to citizens. To everyone: victims and attackers. An end to the 20th century in turmoil full of fear and powerlessness toward an overwhelming force.
