1971 film directed by Petr Schulhoff

A group of children are investigating a chain of mysterious events during the seventies.

Teacher Majer is released from prison under an amnesty. His elementary school classmate Ivan, who lives in a Roma ghetto, takes him into his home. Majer has no family. He has no one left, so he welcomes Ivan's offer. Ivan tells Majer that he has decided to help him mainly because he needs to reopen the school where Majer used to teach and briefly served as principal. Living in the ghetto, Ivan is familiar with the problems of his community and knows that the closure of their beloved school has not been good for them. Majer begins to reach out to his former colleagues and, above all, his students to ask for their help. Many of his students also have children of their own. He experiences a number of comical situations with them. However, he has no idea that he is still being watched by Dostál, the eldest member of the mafia family, who knows that Majer has been released and decides to avenge his son and grandson.

A stout middle-aged physician whose marriage has come apart establishes a practice in a small town. Gradually he's drawn into the lives of his patients—a childless couple, a pregnant girl with a stern mother, the son of a duck farmer—and each relationship reveals a bit more about him and the idyllic but insular community.

The fate of father and son Horáček, but this time they switched roles. Jirka has married, settled down and grown up, while his father is in trouble because he has "second lymphoma" and, feeling that he is missing the last train, he starts a relationship with a stripper, Ala, dyes his hair, but mostly he likes a pretty and kind nurse, Lucie. Although he behaves in such a way that it seems to others as if he has lost his mind, everything turns out well, of course.
