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.
