 In the middle of Vienna stands an old tenement building, and time has left its mark both on the house and its inhabitants. Here, time passes at a strange pace. Floor by floor, the visitor can discover small self-contained worlds: grousers, collectors, the forgotten, people with obsessions, concealed and exposed passions. Behind securely locked doors, each prepares his own heady brew. Then, however, death makes its entrance for the first time, sweeping through the stairwell. The owner of the house, a resident himself, dies. His nephew, an entrepreneur, inherits the building and acts immediately. He moves out, takes up lodgings, hands out notice to quit, renovates and devastates. One goal hovers before his eyes; to get rid of the tenants and make money out of the property. Gradually, the closed doors begin to open, and with each outrage committed by the new owner, the residents are drawn closer together. What comes to light thereby is an anthill full of life, and once it opens up, a flood of comical individuals streams out of it, all fighting for their own living space. A minor official, plagued by persecution mania, fears a dreadful end to the matter. Though the signs he sees of this are all wrong, nevertheless, in a furious finale, the outside world descends upon the house and his inhabitants.
