Five young, pretty female athletes are training for an international skydiving contest. From heaven they basically fall straight into the arms of five charming young men. Their coach is less than thrilled about the flirtation and urges his athletes to concentrate on the contest. He is convinced that love-making will put the victory to risk and asks them for sexual abstinence. The power of love turns out to be stronger, however, and soon the first love couples find each other.
Adam, Evchen, and Manni are looking at the moon through their home-made telescope. Evchen isn't interested, and dismisses the moon as a lump of cheese. Manni, who is a big fan of technology, sees satellites and a car driving over the moon's surface. But Adam hears the moon speak, and hears it ask for flowers to cover its surface. From then on, Adam is determined to breed a kind of flower that can grow on the moon.
Two school classes compete against each other. The prize for the winner is a trip to the Baltic Sea. Lars, Peter and the group leader Manni are confident of victory in the cross-country game, after all they have gained experience in the game as "Chapaev's cavalry army". The first point goes to them. However, they fail the math Olympiad - an Indian movie was more important to them than learning. And before the soccer match, they split into two groups. Lars leads a pitiful remnant of Chapaev riders, while Peter plays Indians with the others. At the soccer match, they put legs on each other, and the other class wins that point too. After the defeat comes the realization: maybe they should practice "Cosmonaut" together again - until next year's competition.
