Gymnastics professor Vasek Zamberk (Pavel Landovský) would like to get closer to Miss Lenka Stríbrná (Marie Drahokoupilová). He invites her to races and introduces her to his friend Karel, editor in a big publishing house. Karel (Jan Kacer), an experienced seducer, seizes the opportunity. But it seems that the girl is far more interested in Karel's superior, editor-in-chief Procházka (Ilja Prachar). Karel, who is capable of brilliantly navigating his way through all the difficulties of the Communist regime, does not give up. He endeavors to win Lenka over, the more so since he has really fallen in love with her.
