Inside Cocaine Wars

Two DEA agents search Colombian airports in hopes of catching drug traffickers. A close look at an X-ray scan of a passenger who was selected to go through the Body Scanner for additional screening at the El Dorado Airport in Bogota. The Body Scanner workers examine the scans for cocaine pellets.

To stop the flow of cocaine before it hits American shores, an elite team of DEA agents patrol the central Caribbean's waters hunting go-fasts: speedboats carrying exorbitant loads of cocaine that can hit 100 mph. In the black of night, NGC cameras capture a tense game of cat and mouse as agents track and capture the smugglers and more than one ton of cocaine.

The Nat Geo cameras roll as a specialized team of DEA agents hunt down cocaine submarines in Cartagena, a place perfectly situated between Colombia's Caribbean and Pacific coasts. Fully aware that they have to catch it before it sails, DEA sub-hunters go to the frontlines of today's Cocaine War in one of the most remote places on Earth to catch an elusive cocaine submarine.

Every year, Colombia exports nearly 400,000 tons of cocaine- street value $1.2 billion. Traffickers send drugs by cargo ship, private plane, and even submarine, but the most common method is human mules. Motivated by violent threats or the promise of fast money, thousands of drug couriers risk their lives and their freedom to bring these drugs to market.
