Many of the young workers at an aircraft factory near Prague are members of an aviation club. On the one hand, there is the responsible Franta, who is highly regarded by his colleagues due to his understanding nature. Opposite him is the talented aircraft designer Ruda, who is also an excellent pilot, but also hotheaded, undisciplined and condescending towards his colleagues. He starts flirting with the glass grinder Lída, although he knows that she is Franta's girl friend. A conflict is not long in coming. When Franta's glider crashes due to a suspected mistake by Ruda, Ruda is banned for a certain period of time. This is fatal, because both young men were actually supposed to represent Czechoslovakia at the upcoming international gliding championships in Poland.
