In this episode, Gordon joins Dorset police as they arrest motorists driving under the influence of cocaine. He witnesses National Crime Agency officers intercepting drug couriers laden with tens of thousands of pounds on their way to a major deal, and handles 30 kilos of freshly confiscated cocaine as it arrives at a forensics laboratory for testing. Heading to the source, Gordon treks deep into the jungle of Colombia - the world's biggest producer of cocaine - to meet a coca farmer who risks everything to produce the drug, and witnesses the illegal cooking process by which the plant is transformed.
