Ex-Special Forces soldier Jason Fox used to hunt down drug lords for a living. Now, in this dramatic new three-part series, he travels through Latin America meeting the kind of gangster he was once dispatched to take out. This time he’s unarmed and at their mercy as he seeks to understand how the billion-dollar cartels operate. What kind of lives do their members have, what does their work involve, and how do they continue to evade the law? From the underworld kingpins to their foot soldiers, and the assassins who enforce their decrees, to the producers of the drugs to the traffickers who ingeniously smuggle them across national borders, Jason enters the cartel strongholds of Mexico, Colombia and Peru, revealing their brutal hidden worlds.
