This is the story of Dario, who threads his taxi through the streets; of Jorge, who unloads trucks; of Edwin, who works in the police; and of Luis Carlo, who tends the wounded and sends the dead off to the morgue. A former evangelist becomes a hit man. From him we learn what a bullet is worth, a grenade, a man's life... One of them speaks of feeling "the heat of blood," of finding comfort in his mother's prayers when faced with the lifeless bodies of his father and brother-the two of them murder victims...Another comes out from mass to explain why "it's no sin to shoot down a man in the ear." These accounts of their lives are at once exuberant and tragic; between good and evil. "Reality is that we live and die," the two musicians sing out. Strumming their guitars to accompany the film, they exhort us to "Take advantage of every moment, for when all is said and done, life is but a dream."
