The Moonlight Sonata(1988)

Overview:

A female fashion model Anni Stark takes leave from the fashion business and goes to Finland's Lapland for a vacation. Little does she know that there's a totally lunatic bunch of local hillbillies living in a nearby farmhouse. The plot thickens as one of the residents begins to harass Anni, who is left alone in the wilderness with only her dog to protect her. Too bad for her that her dog turns out to have divided loyalties.
