Investigator Adam Kruk, who suffers from violent outbursts, still works under Kolecki in the department. One day, while Kruk is taking part in a raid, a girl breaks into a house and sets a red-haired woman on fire.

Through his investigation, Adam Kruk and his family find themselves in the sights of a contract killer.

After another red-haired woman is murdered, Klaudia is certain that her brother is the murderer. Adam offers protection to a cigarette smuggling leader in exchange for information.

Adam suspects his colleague Kolecki could be the mole. He and Justyna tail him as they continue investigating the murders of the red-haired women, which leads them to Klaudia.

After the factory raid, Justyna and Rudy have to go to Katowice to justify themselves to their superiors; Adam continues to investigate Klaudia and her brother, Cyprian.

To protect both himself and his family, Adam decides to leave the police force. Before he leaves his job for good, he is determined to break up the smuggling rings.
