Meet the Drug Lords: Inside the Real NarcosTV Show

In this episode, Jason visits Colombia - where the global narcotics industry began. Colombia remains one of the biggest traffickers of cocaine on the planet. Jason travels to Buenaventura, a port area through which an estimated quarter of the world's cocaine is smuggled. It is a world of extreme violence, in which Jason meets an active assassin who is deeply troubled by what he does. There's also a look at the ingenious new methods for smuggling devised by the cartels. And on a visit to Medellin, Jason meets Popeye, close friend and chief assassin for Pablo Escobar - a man with 257 kills to his name.
