Marissa finds herself in a splendid mansion, where she has been sent by her wealthy lover for a two-week training in the art of erotic submission. Nicknamed the Slave Castle by its owners, submissive men and women are sent for their own specially crafted tours of intensive training in submission, bondage and discipline. Though Marissa enjoys a good spanking and some bondage play to get her hot, she really isn't submissive at all. At first she agrees to go just to hold onto her lover, whom she sees as her entree into 'the good life.' What she discovers excites and frightens her, but she chooses to stay, having signed a contract that lays out the terms of the two-week internment. She is a stubborn woman, and her interest is piqued by the trainer, an Englishman named Aaron who takes her on a sensual journey of erotic submission that leaves her breathless and longing for more. What ensues is a tangle of misplaced love of Shakespearean proportions, as Marissa's lover discovers his truly submissive soul mate quite by accident, while at the castle, Marissa is falling more and more under the spell of Aaron, whose heart is surrounded by ice that Marissa is determined to melt.
