Russia

S1 E3: In the final part of her epic trek, the British acting legend crosses Siberia. She visits one of the world’s deepest lakes, meets an oligarch and visits Yekaterinburg, where Russia’s last royal family were executed. Moving on to Moscow, she explores Stalin’s nuclear bunker, meets local models and returns to the place where she was photographed in 1966 – which first inspired her to take this trip.
