Her doctor advises her to travel to Rio de Janeiro to rest, and she moves with her aunt to an inherited apartment in Leme. Once in Rio de Janeiro, the rascal Constantino, who is aware of her wealth, courts her and borrows money, clothes and a Mercedes Benz from his friends, pretending he is businessman man. His friends release "stocks" in a parallel stock market, based and supported in the expectation of the possible marriage of Constantino with Cristina. However, the ghost of Coronel Alexandrão appears for her whenever she intends to have sex with Constantino.
