The Five Devils

According to Wikipedia, part of the filming took place in Isère (France), in the commune Le Bourg-d'Oisans and at Lac Bleu, as well as in Île-de-France. I couldn´t figure out why this movie is called The Five Devils. I read somewhere else that the name of the film relates to the five mountains nearby the place the action takes place. I do not think the landscape plays an important role in the film and, definitely has nothing to do with the story being told. Perhaps a more suitable title would be The Scent of Things, considering 'scent' is a strong issue throughout the whole film, which attracts our attention but does not contribute much for clarifying the development of the plot per se. If I have not read a short description given in Mubi about the story, the whole movie would have been even more confusing to me. Vicky´s father, Jimmy, had not seen his sister Julia for 10 years. From what I remember, Vicky and Julia had not met before, up to the day Julia arrives at the family (Joanne, Jimmy and Vicky) house and the story starts.
