This play by Teatro Exprimental de Cali deals with Colombian political violence through the metaphor of "social cleansing," a process that has tainted the country with blood. The paramilitary forces and the guerrillas tend to "get rid" of individuals they mark as "filth": drug addicts, homeless people, prostitutes, and so on. The play suggests that this political process rests on the border that divides folly from crime, a border that is constantly permeated by bullets and shots. Virgilio, the main character, thinks he has the right to perform the "cleansing," to execute "justice," to erect his own court of law. A serial killer, he has developed an obsession with young and beautiful women (of which he is jealous). He has a "shadow" who follows him and contemplates each of his crimes, torn between morbid pleasure and a weak desire to stop him.
