Teacher Tomáš Majer, who joined a former special school in 2010, has disappeared. He arrived at the school several months after his sister Jana, also a teacher, was murdered. During the school year, the boys who murdered Jana Majerová mysteriously died. Tomáš Majer most likely avenged his sister in cold blood.

The second part begins shortly after the death of Michal Dostál, the biggest bastard of them all. Michal's father and grandfather are convinced that teacher Majer was behind the murders of all three students and was avenging his sister's death. They begin to psychologically torment Majer and search for evidence. The new police investigator Karas, who takes over the case from the deceased police investigator Paleček, is also looking for evidence. Karas immediately suspects something is amiss in the deaths of the "bastards" and also begins to focus on Majer, who is now the school principal.
