Miss Hannah runs The Circle, a group of college girls who are trained to service the older lesbians in the town who can afford to pay for their services. Many of the girls specialise in BDSM, submitting to spanking, bondage, and humiliation at the pleasure of their clients. Like Miss Judith, her mentor, she administers a strict regime, with a code of dress and behaviour, along with severe punishments for those who disobey. For her own amusement, Miss Hannah dominates the college’s German tutor, Frau Ledermann, who is tattooed and pieced, then paraded naked in front of the girls, while whipped and forced to teach wearing a chastity belt. When Hannah’s colleague, Mrs. Freeman, attempts to seduce one of her girls against her will, Hannah blackmails the woman, having learned that she’s having a secret affair with the college principal. Hannah then turns her attention to finding a successor to eventually take over management of The Circle.
