A few busloads of holidaymakers from the agricultural cooperative on a day trip arrive to see the show at the Slavia Circus. But, they have bad luck. It is Monday, the day on which the employees have their extra day off. The only person, Bláha, the leader of the group finds in the empty circus is the stage manager Liška and the box-office girl Maria. In a heated discussion, Bláha proves to Liška that the holidaymakers have reserved and paid their tickets for that night three months ago. Unfortunately, in the meantime, the extra day off was moved from Friday to Monday. Nobody remembered that one Monday performance was already booked. After a shorter argument with Bláha, Liška decides that the holidaymakers will have their show. He sends Maria to get the circus artists from all the different places around Prague - from the artists' exercising arena, from their flats, from the Lucerna Palace, and even from the Central Hotel, where one of the female artists is just getting married. They all understand the situation and show up in the circus ring. The success of the evening is even assisted by the always complaining wardrobe man Rudolfek. Only the bureaucratic manager Ostrý, who is trying to halt the performance, is booed out of the circus.
