The Whore.

The young and aspiring writer, Rikke, heads out to the old and abandoned parental house in the remote Norwegian countryside. A girl, not even particularly beautiful one, all alone in a town full of sexually deviant yokels, that's just asking for trouble. After a couple of tense and unsettling encounters, three dimwits rape the poor girl and she plots an excruciatingly painful vengeance for all of them.
