The famous Russian traveler Fyodor Konyukhov, who has conquered the earth's poles, oceans and highest peaks, sets off on a new, his most dangerous journey. He will have to circumnavigate the Earth in a hot air balloon all alone. A whole team prepares the flight, but it is impossible to foresee all the dangers that await a traveler in extreme conditions. Konyukhov finds himself in a hurricane - without communication, without sleep, almost without air, he must only go forward to return to those he loves.
