This film is about as politically incorrect as is possible. Good grief, where to start .......?
It's the early 19th century, and the brothel business is booming. So much so that whorebrokers must travel to every village. An old hand spots a mildly retarded young woman, whom everyone else thinks is totally useless. But he has a "special method" to determine how good she'll be as a working girl. He buys the girl, who knows nothing at all about sex, and sells her to a brothel.
The girl IS a disaster. When asked to entertain a trio of blind loan sharks, she hides behind a screen and watches them mistakenly paw each other. Through her complete lack of understanding about her duties, she manages to remain a virgin after her first three clients, and to nearly wreck the building more than once.
The madam asks an elder worker to instruct the girl. The elder finds that, indeed, the whorebroker was correct. The elder has to take a week off work to recover. A co-worker comments "the room is under repair, and so is the elder".
In total frustration, the madam demands the whorebroker refund the money. To confirm his reputation, the whorebroker shows that the girl is, indeed, as good as he judged. He takes her through all the positions of the kama sutra, with tragic consequences.....
The story is very raunchy, though with no more than discreet nudity (topless at most), and is played for extreme silliness. Though a comedy, the ending is very sad, bordering on pathetic. Overall - worth a look, but you have been warned !
