In this series, author and journalist Simon Reeve travels to Central Asia to "meet the Stans" - Kazakhstan, Kyrgyzstan, Uzbekistan and Tajikistan. His journey provides viewers with a unique insight into these countries' culture and politics. As well as discovering a region teeming with Islamic militants, ruthless tyrants and radioactive wastelands, Reeve also finds a more absurd side to these obscure countries, including an American military base that sells Soviet knick-knacks, a desert full of shipwrecks and a first-rate Beatles tribute band. Part Four: Tajikistan - Sharing an 800-mile border with Afghanistan, the source for 95% of Europe's heroin, Tajikistan is on one of the world's biggest drug trafficking routes. Simon joins the local police on a drugs raid, visits a warehouse with £100 million worth of heroin, and gets drunk with the conscripts. They survive on just $5 a month while patrolling the Afghan border.
