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.

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.
