Robert Manning is a brilliant and handsome Australian professor, who is excited about his research into an illuminated manuscript, containing Pope Gregory's letters, copied in the tenth century and containing some unique and beautiful details. He has a well-received theory on who was the original, talented scribe of the said manuscript, and in time his work brings him into academic-renown worldwide. He is tempted to divorce his dowdy first wife while travelling Europe with his academic work by a stunning, young German model and they become entwined on a journey of sexual pleasure and culture in the streets of European cities. Robert is enthralled by his new wife's charismatic personality and womanly, tight body. She is impressed by his scholarly feats and brilliance. They embark on family life together, indulging in their sexual unity, but his striking wife and young daughter, with their blue eyes and blonde hair, are often the objects of desire for forces of dark and evil. Robert's own promiscuity and insatiable sexual appetite may even tempt him from his young family.
