Otália (Leandra Leal) arrives in the city to work at Tibéria's Castle (Fernanda Montenegro). She carries a few belongings in her luggage, among which a doll stands out, a symbol of her purity. Meanwhile, at the brothel, Cabo Martim (Du Moscovis) has an argument with Chico Pinóia (João Miguel) who, in spite of himself, calls the delegate, his brother, to close the Castle. As the story unfolds, the Cape falls in love with Otália and she dreams of marrying him, complete with a wedding dress and everything. But, provoked by Chico Pinóia, Cabo Martim ends up in prison. And, to free him from prison and reopen the brothel, Otália gives herself to Chico, which leaves Martim deeply hurt.
