LA SIERRA -- hailed by The New York Times as “Courageous! Poignant!” -- traces a year in the life of three young people in a Medellín barrio: Edisón, a gang leader and playboy who has fathered six children with six different women; Cielo, a widowed mother with a paramilitary boyfriend in jail, and Jesús, a young gangster whose readiness for death fuses with his indulgence in drugs.
