Colombia remains one of the world's largest sources of cocaine, and former Special Forces soldier Jason Fox travels through the country to meet the people who move it. He sits down with smugglers who risk their lives ferrying loads worth millions of dollars, cartel enforcers, and traffickers he might once have been sent to hunt rather than interview. Fox brings a particular vantage point to the conversations: he spent years as an elite soldier pursuing drug lords, and now, more skeptical of that mission, he asks the people on the other side how they think, what draws them into the trade, and what they fear. The episode is part of a three-part series that also covers Mexico and Peru, tracing the routes and relationships that keep the cocaine trade running. Interviews are conducted face to face in the field rather than staged, and the film stays focused on individual accounts of the business rather than broad statistics, giving a ground-level view of an industry usually described only in numbers.
