Guy Martin explores Colombia's violent underworld, undergoing the same kidnap training that politicians go through and visiting a bullet-proof clothing factory. To find out more about the cocaine trade, which is a root cause of many of Colombia's issues, Guy loads a motorcycle into the back of a cargo plane and flies into the Amazon, to an airfield cut into the jungle by notorious drugs kingpin Pablo Escobar
Guy Martin continues his tour of the country's secret side by trying his hand at a semi-illegal cycling sport, where the goal is to drop down the steepest mountain roads as quickly as possible on modified bikes, using extra weight to go faster. After climbing onboard a drug cartel's smuggler narco-submarine to see how it could be built in a jungle workshop, Guy gets face to face with a drug dealer and former employee of Pablo Escobar
