Herculan is a Puritan man and has a traditional family. He had only had one woman in his life and promised his son Serginho, while his wife was in agony, that he would never have another woman. His brother, Patrício, on the other hand, lives at the expense of his brother and does everything so that Herculano depends more and more on him and thus can explore him more and more. Taking advantage of his brother's crisis of desperation, Patrício places a picture of Geni, a singer from hell and harlot, at his table. After getting drunk he goes to the brothel, where he meets her and spends the night with her. However, he later denies the connection, but they are already in love. He promises to marry her, but for that he needs to make Serginho travel. However, sensing what is happening, Serginho refuses to leave, but something even bigger will torture Herculano.
