The valley of cocaine

Peru is considered to be the largest cocaine producer at all. It is estimated that hundreds of tons of the drug are manufactured in secret laboratories each year and then exported around the world. The problem: The coca-growing areas between the Andes and the Amazon are barely developed and poor - the ideal breeding ground for corruption and drug trafficking. Journalist David Beriain embarks on a dangerous search for clues to find out more about the illegal cocaine production on site. He meets coca farmers, unscrupulous drug smugglers and the military who risk their lives in the fight against the "Narcotráfico".
