Thanks to the law of 1948 and to her grandmother, the nominal tenant who is always absent, Francesca Cigalone and all her tribe (thoughtless husband, orphan sister, self-centered film maker and his mistress of the day, eccentric granny, friends, friends of the friends, daughter...) live on a shoestring in a very big apartment. Which is not to the liking of supercilious bitchy owner Charlotte Falingard, who has been intent for some time on having them evicted for obvious speculative reasons.
