Ghost Guns (S01E01)

To get away with a crime, criminals look for completely untraceable guns. Enter the "ghost" gun: an exact replica with a fake serial number and no ballistic record — a gun that is potentially invisible to law enforcement. Craftsmen in the Philippines specialize in making some of the highest quality ghost guns in the world. We follow clones of .45 automatics from a Filipino backyard workshop into the American black market. But ultimately even ghost guns leave a trail. Then they become "burners," guns so hot no one wants them, except in another country, where the gun's criminal history is difficult to trace. We follow the burners to Guatemala — a dumping ground for black-market guns — and into the hands of a 14-year-old hit man. A chilling investigation into the world of international criminality, this episode has unprecedented access to the underground world of manufacturers, sellers and gangsters — whose business and brutality all depend on the violent, illegal arms trade.
