When an apparently harmless landslide strikes the tiny mountain village of Vallata, some of its residents begin to suffer from a mysterious form of amnesia: six years of their lives vanish without a trace. Relationships, children, life-changing decisions — all forgotten. The village is placed under quarantine, and no one outside knows what is really happening. But Matteo, a war reporter originally from Vallata, manages to slip past the authorities in search of the truth. He joins forces with Alma, an oncologist who was in the area on a hiking trip and has become stranded in the village.

It soon becomes clear that the amnesia is only the tip of the iceberg. Those who have lost their memories begin experiencing strange visions that grow more vivid with each passing day, eventually feeling more real than reality itself. What terrible truth lies behind this unsettling phenomenon? Is it a disease, a curse, or a dark and long-buried past that is now demanding to resurface?
