On their 30th birthday, identical twins Paul and Hansen Hoepner set off on their longest bike tour. For the huge distance from Berlin to Shanghai, the two only have seven months of sporting activity and hardly more equipment than sleeping mats and a small tent. The journey takes you through Poland and Russia to the wasteland of the Kazakh steppe. You cycle through the bizarrely beautiful landscapes of Kyrgyzstan and the sandstorm-whipped Taklamakan desert, up to 5,200 m high passes in the Himalayas. As much as the two are outwardly similar, their character is just as different: Paul is a forward-looking realist with a penchant for planning and a false bottom. Hansen, the daring adventurer, prefers to leave things to fate. What neither of them knew beforehand: That makes the tour the trip of a lifetime, with moments of greatest happiness and painful crises, during which they get to know themselves and their twin brother in a completely new way.
