Tram driver Marie has far too much to do after her shift is over. But she likes to do it all since she loves her husband Václav sincerely. One day she spots him on the Lesser Town Square in Prague, kissing an attractive blonde good-bye. It seems to Marie that her small comfortable world has collapsed and she walks out of the tram in tears. But her sadness does not last long. She wipes off the tears and begins to act. She withdraws all the money from their savings books and buys off all the latest models from the Fashion Works. The visit to the beauty salon then completes her transformation into a lady.
A young man tries to enter the building of the Mammoth Cybernetic Supermachines Research Institute again and again but each time the doorkeeper spots him and kicks him out. The youth finally arrives with all his friends and a huge live bear from the circus where he works as an accountant. He is finally allowed in where he explains to the members of the directorate that he wants to work at the Institute, since he graduated in cybernetics and, besides, he has invented a machine for forecasting time of death. When the conniving research manager learns that their director is going to die in two days, he hopes to rise to his position.
