[citation needed] André (Curado Ribeiro), is a son of a wealthy family who meets a girl called Luisinha (Milu).

When all seems to be going according to plan, enter Ms. Mafalda da Silveira (Maria Matos), André's aunt, who unmasks her nephew and ends the farse.

André gets injured in a car accident, and takes advantage of his ailment to persuade his aunt with the help of his uncle Simão (Manuel Santos Carvalho), to allow Luisinha to live at her mansion, to attend him.

One day, Simplício Costa comes to the mansion at the request of Simão and, unexpectedly, he finds the lost love of his youth, gone for over 30 years: Mafalda.

All seems perfect, but one person stands before in André and Luisinha's happiness, Isabel de Castelar (Teresa Casal), an ambitious woman coveting Daniel's fortune.
