Ciudad Juarez was once a symbol of Mexican industrial growth; by the time this episode of Fault Lines arrives, it has become known as the murder capital of the world, with more than 8,000 people killed since 2008. That was the year President Felipe Calderon sent the army into the city as part of his offensive against the drug cartels, and the official account blames the killing on the Sinaloa and Juarez cartels fighting over a border crossing that sits only a few hundred metres from the multi-billion dollar US drug market. Host Josh Rushing travels through Juarez talking to residents, officials, and people caught between the cartels and the military, tracing how a factory town turned into a war zone and who benefits from it staying that way. The film's question is blunt: how did human life here come to be worth less than the drugs moving through it? Rushing lets the body count and the impunity around it answer.
