Ulisse, Fulvio and Domenico decide to rent an apartment together in order to live with their modest work. However the three encounter any difficulties that have forced them to always be one step away from starvation. Ulisse has to maintain his wife and daughter selling recordings of important foreign singers, Fulvio has the task of reviewing silly scandals of celebrities instead of writing articles for major artists, while Domenico must keep his wife and children going to make love with old single pensioners.
Unfortunately the movie A Flat for Three is not yet available on HBO Max.
