Gruppo di famiglia in un interno

Retired American professor (Burt Lancaster) lives a solitary life in a luxurious palazzo in Rome. He is confronted by a vulgar Italian ''marchesa'' (Silvana Mangano) and her companions: her lover (Helmut Berger), her daughter (Claudia Marsani) and her daughter's boyfriend (Stefano Patrizi) and is forced to rent to them an apartment on an upper floor of his home. From this point on, his quiet routine is turned into chaos by his tenants' machinations, and everybody's life takes an unexpected but inevitable turn.
