Vidago Palace has the background of the year 1936 and tells us a love story between two young people from different classes, ready to face all obstacles.
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?
