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.
