Hynek Michánek wants to study medicine but fails his entrance exams five times. He starts a job as an orderly in a district hospital where one of the doctors on the examining board works as well. He feels no-one takes him seriously and he loathes the doctors, who treat him with disdain. When an old man begs him to end his pain and suffering by helping him to die, Hynek gives him a "liberating" injection. But now he has done it once, he finds he can't stop. He continues killing other patients, even though he knows he can't get away with it for long.

Two classmates, the hard-working and honest Eva and the hot-tempered Petr, collect the most waste in a school competition and are rewarded with a trip to the sea in Bulgaria.

The eponymous castle is the setting for three stories that gradually intertwine. Castellan Vašek offers a place to stay at the castle to singer Jana, who is trying to hide from her angry boyfriend. He is jealous of her and sets out to look for her at the castle with his bandmates. Local man Olin is looking for his wife, who is rehearsing a folklore performance for the village anniversary and has not arrived home, and due to a misunderstanding, he also searches the castle. The last actor is a thief who tries to steal a rare painting from the castle and has to flee from a polar bear. How will this confusion turn out?

The reason for making this film is clear: it was to cover up Vojtěch Jasný's famous chronicle "All the Good Natives", an account of the tragic consequences of forced collectivisation. The pro-regime director Antonín Kachlík also focuses on the socialisation of the Moravian village, accompanied by mistakes and coercion, but in his optimistic view he emphasises the hopeful prospects leading to a happy future. Although the united village lands were born in pain, they will serve for the benefit of all the working people... As with Jasný, Radek Brzobohatý embodies the stubborn peasant, who is only slowly acknowledging the benefits of communal farming. However, unlike the poetic exuberance and pithiness of Jasný's chronicle, here we encounter a vicious posturing.
