Gente Fina É Outra Coisa (1982)

The Penha Laredo, completely ruined, needed money. The family entrepreneur then has the idea of receiving in his mansion, rich guests that could help restore the family finances. But there was one problem: the matriarch of the family (Amelia Rey Colaço) could not know they were guests and therefore they had to pretend to be distant relatives who came from afar.
