Chinese kamasutra

Joan Parker, an American scholar of Chinese lore, recently took on a job at a Chinese library. When she stumbles upon a volume of the Kamasutra, her sexual fantasies are unleashed, but she remains cold towards the advances of her fellow librarian. There seems to be a connection to a haunted house she passes by on her way home, and the strange man keeps watching her from a barred window above. Unknowingly, she stumbles into the clutches of the Kamasutra cult, and through a series of trials and orgies discovers her sexuality…and her true nature as a reincarnation of an unhappy lover
