1962. Johannes Leinert travels to a physics congress in the Swiss Alps, where an Iranian scientist is set to reveal a groundbreaking theory of quantum mechanics. But when the physicist arrives, the Iranian guest is nowhere to be found. Johannes remains at the hotel and develops a special fascination with Karin, a young jazz pianist. But something about her seems strange. When one of the German physicists is found dead one morning, two inspectors arrive on the scene, investigating a homicide case. As increasingly bizarre cloud formations appear in the sky, the pianist disappears without a trace —and Johannes finds himself dragged into a sinister story of false memories, real nightmares, impossible love and a dark, roaring mystery hidden beneath the mountain.

Winner of the best direction award of the Jury of Independent Critics at the Venice International Film Festival.
