They rule that when they get to the mansion their daughters must be completely naked at all times. They recruit four teenage boys to act as guards (dressed with uniforms of Decima Flottiglia MAS) and four young soldiers (called "studs", "cockmongers", or "fuckers"), who are chosen because of their large penises. They then kidnap nine young men and nine young women and take them to a palace near Marzabotto. Accompanying the libertines at the palace are four middle-aged prostitutes, also collaborators, whose job it is to orchestrate debauched interludes for the men, who sadistically exploit their victims. During the many days at the palace, the four men devise increasingly abhorrent tortures and humiliations for their own pleasure. During breakfast, the daughters enter the dining hall naked to serve food. One of the studs trips and rapes a daughter in front of the crowd, who laugh at her cries of pain. Intrigued, the President moons several slaves before prompting the stud to perform anal sex on him and the Duke sings 'Sul Ponte di perati'. Signora Vaccari uses a mannequin to demonstrate to the young men and women how to properly masturbate a penis and one of the girls tries to escape, only to have her throat cut. Signora Vaccari continues with her story. Two victims, Sergio and Renata, are forced to marry. The ceremony is interrupted when the Duke fondles several victims and prostitutes. At the end, Sergio and Renata are forced to fondle each other and the men rape them to stop them from having sex with each other. During this, the Magistrate engages with the Duke in three-way intercourse. Another day, the victims are forced to get naked and act like dogs. When one of the victims, Lamberto, refuses, the Magistrate whips him and tortures the President's daughter by tricking her into eating food containing nails. Signora Maggi relates her troubled childhood and her coprophilia. As she tells her story, the President notices that one of the studs has an erection and fondles him; another stud uses a female victim's hand to masturbate himself. She also explains how she killed her mother over a dispute about her prostitution and Renata cries, remembering the murder of her own mother. The Duke, sexually excited at the sound of her cries, begins verbally abusing her. The Duke orders the guards and studs to undress her.
