The Teacher

After the body of a local student is found in a forest, the police discover that she was murdered. New teacher Pawel Zawadzki arrives at her school, but his reason for leaving his city job is unclear.

Students reveal Joanna was unpopular, and the police tell her boyfriend Maciek that she was pregnant. Ewa, Joanna's mother, is shocked to see her daughter's biological father, Pawel, at the funeral.

Daniel, the PE coach at the school, is arrested by the police, but Pawel finds evidence to clear him. Shady local businessman Grzegorz Molenda holds a party, and Maciek finds a video of Joanna.

The video convinces Maciek that Grzegorz's eldest son, Sebastian, is the murderer so he steals a gun. Sebastian's brother, Jasiek, tries to become part of a gang led by Adrian, Grzegorz's sidekick.

Sebastian and Pawel exchange favours to play down Maciek's shooting. Grzegorz works on an illicit deal. The prosecutor orders DNA and blood tests from the Molendas to see who fathered Joanna's child.

Grzegorz is arrested for Joanna's murder after his plan to have the blood samples switched is uncovered. Ewelina, Joanna's close friend, discovers that the land Grzegorz wants to sell is polluted.
