Peter, together with his equally sadistic father, continues to use the women they own in the most perverted ways.

After a year of painful service, Maggie hopes for some sympathy from her horrible master, but Peter remains apathetic to the suffering of the poor slavegirl.

Maggie and her slave-mate Sherry also have to put up with the terrible attitude of Peter's girlfriend Anna, a mysterious foreign exchange student with immunity from the compulsory female slavery law.

Serving a free female is worse for the poor girls, especially one with violent sadistic tendencies and skills to abuse other females.

Anna uses her status as Peter's girlfriend to sadistically play with girls, and even teaches them tricks to please herself. Anna becomes more and more assertive, creating tension among Peter's slaves and friends alike.

Hiding behind her immunity, she doesn't hesitate to insult male students and seduces female students with total disregard of the social norms. Eventually tensions flare in a friendly gathering, where Peter has a falling out with one of his closest friends.
