Art historian Lissa and doctor Colin meet at the Frankfurt Book Fair, where they are both promoting their latest books. At the fair, and then through Europe, the two lovers embark on an exploration of their sexual fantasies, playing intense games of bondage, spanking and dressing up. Lissa loves humiliation, and Colin is just the man to provide her with the pleasure she craves. Unbeknown to Lissa, their meeting was not accidental, but planned ahead by a mysterious patron of the erotic arts.
