Two musically gifted young cousins, Max (the girl with the boy's name) and Toni (vice versa) have been brought up under the tyrannous rule of Aunt Charlotte. Their lives are dramatically transformed when Charlotte gifts them to the charismatic Professor Labat, known as The Maestro. His talents extend far beyond his musical genius, and he prepares his proteges for a novel kind of serfdom, in which their skill is combined with erotic artistry to refresh the jaded palates of the wealthy clientele in The Pleasure Dome, mansion of the notorious Lady Letitia (Titty) Laycorn.
