Swiss documentary filmmaker Fredi M. Murer turned to fiction-and near-surrealism--with Alpine Fire. Thomas Nock plays The Boy, a mute teenager who falls in love with his own sister Belli (Johanna Lier). The Boy is isolated on his family farm by his parents, who aren't cognizant of his feelings towards Belli when they order her to educate him at home rather than send him to school. Unable to reconcile himself to his yearnings, The Boy runs off to a secluded alpine cabin. The deaths of the parents--one by natural causes, the other by murder-leaves The Boy and Belli alone at last. Filmed in 1985, Alpine Fire was released to the American film-festival circuit two years later.~ Hal Erickson, All Movie Guide
