On an international flight from Rio to London, Corey meets Eulalie, who is clearly distressed. For Eulalie has accidentally - or deliberately? - been booked in to the Kenwood Institute, a charitable foundation for the education of sexual novices. When the two women realise how similar they are in appearance, they decide to swap identities - and passports. Thus begins Corey's rigorously competitive training in the sensual arts, which culminates in an orgy at a masked ball in Venice. Will Corey win the coveted jewelled Venetian mask? Or will her newly aqcuired talents bring her even greater rewards?
