Zay boards the infamous Ice Train for a wintry trip to the far north of Siberia, deep inside the Arctic Circle on the world's most northerly railway line. His journey takes him through Tobolksk to the gas fields of Novy Urengoy, follows the abandoned route of Stalin's "Railway of Death," visits a Communist gulag, camps overnight with the Nenet nomadic tribe, and finally crosses the wilderness to reach Labytnangi and the newly opened Bovanenkovo gas field.
