The Engineer is a cross-platform documentary from the award-winning Guerrilla Pictures. It offers a unique take on El Salvador's brutal gang conflict through the eyes of a man whose life revolves around murder.

And the police vent their frustration at a lack of resources. With more than one hour of HD video, this app is a unique gateway into an unreported world of pain and bloodshed.
