Case in the Desert(1957)

Gliding competitions are taking place in one of the border towns of Uzbekistan. An unexpected typhoon blows a glider with schoolchildren Kostya and Rustam into the desert. When their glider crashed on the sand, the guys find a small Firyusa in the cabin under the seat, who really wanted to fly, but they didn't take her. The three of them set off across the desert to the Dead City.
