Our Guy in Russia

In Moscow, Guy rides with Vladimir Putin's biker gang, persuades a mysterious man to let him drive his Zil limousine through Red Square, and performs an aerobatic display in a Soviet air force jet

Guy Martin continues his 10,000-mile adventure around Russia to find out how the biggest country in the world really works. His journey in this episode starts in Archangelsk, a remote city in the frozen north that is home to Europe's only diamond mine. Guy works at every stage of this billion-dollar process, from driving one of the world's biggest dumper trucks to witnessing a laser saw cut a 200-carat diamond worth millions of pounds. He then realises a lifetime ambition to visit Kamaz, Russia's biggest automotive manufacturer, and drive one of their famous Dakar Rally-winning trucks, before visiting the Kalashnikov factory to see how the AK47 - the most popular gun in the world - is made.

Guy Martin leaves Russia and visits Chernobyl in Ukraine - the site of the biggest nuclear disaster in history - to explore the record-breaking engineering solutions designed to make the area safe, 32 years after the nuclear power station exploded. After receiving specialist training about how to avoid contamination, Guy is allowed into the most radioactive place on Earth, a restricted exclusion zone of 1000 square miles. He heads straight for the breached reactor, which is now entombed within a 36,000-tonne shelter called the New Safe Confinement. He climbs to the top of the structure, which is taller than the Statue of Liberty, to carry out a radiation survey, and finds an area that's so radioactive that he's only permitted to stay for 20 seconds. Guy interviews a surviving 'liquidator' - one of the volunteers who helped clean up the immediate aftermath of the explosion - about the ad-hoc protective clothing they were given to wear, which was made of lead.
