In episode 2, Gordon continues his journey through Colombia to the epicentre of the production line supplying Britain. At the forefront of the drug war are the SAS-trained elite squad known as the ‘Anti-Narcoticos'. They have identified a huge plantation of coca leaf they believe is run by the cartels and take Gordon on a 90-minute helicopter flight through the jungle, to kill the crops with a chemical spray.
