1978. The kidnapping of Aldo Moro – and his execution. A state of emergency is declared in the cities. Drugs are rampant. Three popes in the Vatican. The last great social reforms. While all this is happening, more and more Italians are seeing flying saucers day and night. It is a mass phenomenon, the "Great Wave." Two thousand UFO sightings in the Italian sky, dozens of "close encounters of the third kind" with intergalactic travelers. Aliens and spaceships flood pop culture.

Milena Cravero, a young anthropologist, studies "ufologists" in a dark and militarized Turin. Martin Janka, a successful author, has told stories about ancient cosmonauts, but he is tired of himself – and tired of Rome. His son, Vincenzo, a former heroin addict, lives in Thannur, a commune in Lunigiana, on the slopes of a mysterious mountain. The Quartzerone, with its three peaks. A place filled with myths and legends, unexplained phenomena, and unsolved cases.

The most recent one is that of Jacopo and Margherita, two scouts who disappeared in the forest and were never found. Around their disappearance, a whirlpool of stories and characters.
