Adaption of the Antonin Dvorak opera Čert a Káča (The Devil and Kate), Op. 112, B.201, based on a farce by Josef Kajetán Tyl.

Karel Doležal, insurance clerk and exemplary father of a family, leaves for a business trip with his secretary Vlasta. After spending the night together, they both return home. However, thanks to a small moment of inattention, they run over the boys. Karel runs away from the scene of the crime. He won't tell anyone what happened. Then when he reads in the newspaper that the boy did not survive the accident, he begins to feel guilty. He confides in his wife about the accident, not the infidelity. Their son Jirka overhears everything. His father has always been his role model, and that's why he doesn't want to accept his guilt.

Jaroslav Hašek screens four film stories in the fairground shed around 1900. After period advertising slides and a "newspaper", we see "the first part of a sensational, exemplary, parfuss, salon program - a film from the life of school-age children, shot under very difficult circumstances". The plot of this film takes place partly in a school classroom and partly in a gymnasium toilet, where the primate Chocholka took refuge from a Latin composition. "Exemplary Family Happiness" is the second film that takes the viewer into the family of the municipal official Honzátek, in which many stormy scenes occurred when the hamster, provided by Honzátek Jr., moved into the sofa - a wedding gift from Sister Ema. Equally surprising are two other stories, one of which tells about the "father of the poor", the owner of a company with unrecoverable cash flow and a famous patron, and the other about the fateful consequences of a joint trip between the old bachelor Mr. Hanzlíček and his neighbors.
