To mark the 100th anniversary of the Russian Revolution, Simon Reeve sets out on a journey across the vast and diverse country. He begins in Russia's far east among the active volcanoes of the snowy Kamchatka mountains, the coldest inhabited region in the world. Here, reindeer herders live in temperatures as low as minus 30 degrees. Outside the eastern port of Vladivostok, Reeve observes the growing influence of China, but soon his crew are being followed and harassed by the authorities. Passing through the Boreal Forest, Reeve seeks out a conservationist dedicated to protecting the endangered Amur Tiger. Environmental concerns come to the fore again when he ventures to Siberia.
