Small arms are the real weapons of mass destruction: killing more than half a million people a year, spreading like a disease and destabilizing entire regions. Beginning in the gun markets of Somalia we travel within the region where guns are making life a misery of violence and fear. But no guns are made in Somalia. From France, to South Africa, from Bosnia to Moldova , the United States and Canada, we travel around the world to examine ways in which the guns slip from legal to illegal markets, via the so-called Grey Zone. From dealers to pilots to end-users, to the victims, we witness a largely unregulated trade in what has become the globalization of death. When 200,000 AK47's go missing from Bosnia stockpiles and are flown on illegal flights to who knows where, activists try to push initiatives to curb the trade at the UN. But the call for a treaty similar to the Land Mines Treaty is blocked and- loopholes "large enough for Antonov-12s to fly through" continue to destabilize our world.
