Belfer: Season 1

The body of high school student Joanna Walewska is discovered by three of her peers. Police initially believe that she may have committed suicide, but they soon find out there is more to the incident.

Police begin to interview students, under the supervision of their principal. They are joined by a psychologist, as they learn more about who Joanna really was.

The mood in the town grows sombre as the investigation begins in earnest, and disrupts some illegal activities. The police begin to suspect the local high school sports teacher, Daniel Poreba.

Pawel continues with his own investigation, with the help of local reporter Lechak, who is providing access to documents. The details of the contraband liquor trade are determined, so the plan can go ahead.

Maciej remains in hospital, near death, watched by Ewelina and his father Jacek. Pawel makes a tempting offer to Sebastian, and the prosecutor asks for DNA samples from suspects.

Marta realises that the deed of sale for the property is partly fraudulent after examining it more closely. The police discover that some of the DNA samples were tampered with.

Joanna's mother opens up, which helps to clear one of the suspects of foul play. This leaves Pawel in a compromising position, as he was convinced of the suspect's guilt.

The criminal brigade are forced to rally and take action after an impressive escape. Pawel is convinced that Adrian is innocent, and calls on his colleagues to help question him.

Lieutenant Kedzierski is alarmed by the surgical precision conducted in another recent murder. He realises he needs Pawel's help, and asks him to formally aid the police.

Youlka becomes heavily implicated in the murder of Joanna, due to a damning video. However, Pawel finds that things are not as simple as they seem, when he is called to interview Youlka himself.
