A hardened Czech lesbian warden, her eyes as cold as the bars of her prison, takes it upon herself to initiate a new inmate into the cruel, sexual world of lesbian BDSM. The warden, a Mistress in every sense of the word, deploys her arsenal of whips, handcuffs, and her own sadistic desires to mold the young lesbian into her perfect submissive. The ward's office becomes a stage for their intense, taboo relationship, with the warden's whip echoing through the halls, punctuating the inmate's cries of pain and pleasure. As the days wear on, the inmate's body bears the marks of her training, a roadmap of her journey into the dark, exhilarating heart of lesbian BDSM.
