A group of classmates is invited to stay at a spa. However, they experience many twists and turns, funny situations, but also personal dramas. At the same time, we follow the story of a young thief who gets a job as a cook at a luxury spa hotel and experiences his first great love when he falls for a beautiful maid.

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.
