The hard-working head of the farm machinery maintenance crew, Lawrence, is always in control. He knows how to keep everyone around him busy, and he loves to meddle in the affairs of other members of his large family. Above all, he has high hopes for his promising daughter Štěpánka. He wants her to become a college student. But everything gets complicated when the girl falls in love with Tomas from the neighbouring village. One of Vavřince's latest excesses is to prepare a wedding that he doesn't know is no longer necessary.

Police find a girl with a bleeding face in a small town park at night. First the girl, a textile factory worker Jana, refuses to talk, and then she decides to tell the truth. After her father's death she, by herself, takes care of her younger brother called Pinda. She does not like the influence that a gang of older boys from the factory exercise over her brother. The gang leader Jirka, called King, is admire by local girls whose number exceeds boys in the town because there are many textile factories where only girls are working. They easily yield to him and then he easily gets rid of them. Jana is a hard nut for him. She refuses his purposeful courtesy and thus she unintentionally gets his attention. King inspires the gang on how to get money by stealing textile from the factory warehouse.
