Hana Sikorova, mayor of the dying village of Pustina, battles the powerful coal company that wants to expand and obliterate her town. Then her 14-year-old daughter, Misha, goes missing.

The Criminal Investigations Unit looks into Misha's disappearance. Hana suspects the coal company may be behind it, but Inspector Rajner thinks a 16-year-old juvenile delinquent who has been secretly seeing Misha may know more than he lets on.

Karel is interrogated and released, against police wishes, following an intervention by the district attorney. Meanwhile, Hana gets an inkling that Misha may have had a secret life.

Karel discovers a link between one of the boys from the juvenile facility and a man who works at the mine company. Hana uses the information to force the company's owner to pressure the police to expand their investigation.

The police seem to hold all the necessary evidence to close the case, but Karel is convinced they are on the wrong track. He realizes that if he wants justice to be served, he will have to take it into his own hands.
