Pedro, dressed as an employee of the Vidago Palace, enters Carlota's room at night. The two have many explanations to ask each other. But Livia's arrival prevented them from speaking. They agreed to meet at the cabin the next day.

On leaving, Pedro crosses with the sisters Perliquitetes, who recognize him and are scandalized, because they knew about Pedro and Carlota's relationship. The sisters are in fleas to tell the Countess what happened.

The next day Carlota and Pedro meet in the hut. The two are hurt with each other.

Carlota, because when she had to return to Lisbon, she wrote a passionate letter to Pedro, of which she had no answer, and when she returned to Vidago she learned only that Pedro had gone to fight for Spain.

Pedro, because when he read the letter, Carlota told him that everything had been a mistake and put an end to his novel.

As they talk to each other about it, they realize that the letter Carlota wrote and the letter Pedro received aren't the same. What has happened, then? Carlota finally realizes everything. It was her mother who changed the letters.

When the sisters Perliquitetes are almost telling the Countess that they saw Peter the night before, Carlota arrives and confronts her mother by showing her the fake letter. Lívia and Carlota argue. Carlota tells her mother that she is not going to marry César Augusto. Lívia tries as she can, to hide the situation.

But Carlota is determined. That night she goes with Pedro with the popular party of Vidago. She feels free. The problem is that César Augusto is there and he sees Carlota and Pedro kissing. César Augusto loses his temper...

Pedro doesn't even believe Dolores kissed him. He makes it clear to her that his heart belongs to Carlota. They are interrupted by Inspector Lopes who informs them of something that surprises them: Pedro has friends who will be able to set him free. Pedro, instinctively, says he's not going anywhere without Dolores. Lopes, in an apparent good mood, grant him the wish.

In fact, the Inspector's plans are different. After accepting a lot of money from Benvinda de Fátima to free Pedro, Inspector Lopes orders his subaltern Sergeant Fernandes to shoot Pedro and Dolores as soon as they're released, so as not to leave evidence of their corruption.

On the eve of the wedding day, Lopes and César Augusto talk. César , upset, says that if he catches Pedro, he kills him with his own hands. Lopes reveals that this will happen the next day, because there are already those who have decided to do it for him. César becomes pensive.

The wedding day finally arrives. In the Church full of guests, Carlota and César Augusto stand before their families and the priest. Will Carlota give the "yes" to César Augusto, in order to save Pedro?
