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.
