Martha awakens in a strange room with only the vaguest memory of how she got there. She remembered being out with two girlfriends and being bought drinks by three good looking men -- but after that... nothing.
Things get worse when she meets one of the men from the previous night, who assures her that she signed up for a job that they offered her: A public escort for high powered clients who need a female partner for appearance at business meetings.
While it all seems rather suspicious, she is wined and dined into acceptance of the story - especially after learning the amount of money she will be paid. However, after being presented to her wealthy client, and driven off in a limousine, she is rudely informed by this man that she is his property, bought and paid for. Things go from bad to worse when she is flown to a remote castle in Romania and learns the full extent of her fate: that her owner sees himself as a modern incarnation of the Marquis de Sade.
Somehow, she must survive the predations of this capricious and cruel man and his cronies, along with the other girls imprisoned with her. Befriending her roommate in the castle's seraglio, they determine to escape, but the task is a formidable one and one that taxes her ingenuity to the limits. Will she survive the ever increasing obstacles in her way and finally get back to civilization?
