Here is the Cine Lumiere introduction:
A mystery lurks behind the apparent tranquillity of an Alpine village. As a storm approaches menacingly in the background, Pietro, a young expert technician, comes to the valley to repair a malfunction at the high-altitude electrical plant. He is suddenly involved in a strange disappearence. When the young man figures out the origin of the secrets hidden in the heart of the valley, the tensions explode with extreme cruelty and spark a play of distorting mirrors in which everyone falls under the lens of suspicion.
The film will be preceded by an introduction and followed by a Q&A with Claudio Noce
