Trabants have traveled the world, now frogs are swimming! Traveler Dan Přibáň returns to cinemas after six years – this time in an amphibious vehicle LuAZ 967 nicknamed the yellow frog, which not only drives, but also swims! Together with him, a Czech-Slovak group of crazy adventurers, including the indestructible Marek Slobodník on a floating motorcycle tricycle, set off on a wild journey. The goal? 18,000 kilometers from Prague to Ulaanbaatar. The means? Used, dangerous and funny machines. The challenges? The pitfalls of exotic countries, bizarre regimes, disappearing rivers, blooming deserts and endless plains where there are no roads – only directions. And Mongolia – the land of blue skies. The least populated country in the world. A country that breaks hearts and fulfills dreams. In the finale, under the dunes of the Gobi Desert, the moved guys discover that it was really worth it and that miracles do happen... But sometimes completely differently than they expected.
