The film is essentially a feature-length commercial for an exhibition to mark the 40th anniversary of the nationalisation of the Czechoslovak film industry, to be held at the Prague U Hybernu venue. The protagonists of the piece are comedians Oldrich Kaiser and Jirí Lábus, who are set to accept an award from Japanese television representatives at the exhibition. At the same time, five gangsters plot to seize a revolutionary invention devised by professor Suzuki - a super holograph, which enables any figure from television to be transported in the flesh into the real world, and vice-versa.
The Francs with their daughters Olina and Jirina are building a villa in the village of Rezkovice. Father Franc (Vladimír Mensík) doesn't allow himself a minute's respire and restlessly forces to work his wife, both daughters and Zdenek, Jirina's suitor. Zdenek does not protest against it and, in addition, he is skillful. On the contrary, Olina's boyfriend Libor is worse at work. He studies at the Technical College and he does not succeed much in grasping the building handicraft. Franc, proud of his pursuits, decides that he will arrange the wedding for both daughters and then hand them over the key of the villa in which both pairs have luxuriously furnished flats.
Set in Prague during the years leading up to World War II, this family saga tells the story of a cobbler named Vincenc Bursik (Vladimir Mensik), who uproots his clan from the country to the city, only to suffer the loss of his wife and the failure of his shoe business within months. When his daughter moves away to go live with a wealthy businessman as his mistress, Vincenc is left to take care of his two sons, who spend their days in a secret garden vying for the affections of a teenage girl.
Mr. Tau, the quiet and kind magician with a bowler hat and an umbrella, shows up unexpectedly on the wings of a plane during flight. The terrified crew contact the airport security service. After the plane lands, Mr. Tau disappears. The third security inspector Málek is determined to catch the hooligan at any price. To achieve this, he gives up his holiday to visit the children's summer camp. Mr. Málek's son, who just like all the other children is delighted by the new camp cook, Mr. Tau himself, has unknowingly set the inspector on the magician's trail. But the children at the camp are determined not to let their beloved magician get caught and ingeniously place all sorts of traps in Inspector Málek's way.
