S1, E3: In the final episode, Joanna is in deepest Siberia heading for Moscow, which she last visited in 1966. Her first stop is Lake Baikal, one of the deepest lakes in the world. She drinks vodka with a local fisherman before getting back on the train for Krasnoyarsk where she meets an oligarch. From there it's across the vast expanse of Siberia to Yekaterinburg, a city with a dark history. It is where the Russian Royal family were murdered. Joanna pushes on for Moscow, where she discovers a very different city from the one she saw in the sixties. She visits Stalin's nuclear bunker and encounters Russian models, before finding the place where she was photographed in 1966, which inspired the whole adventure.
