October 27th, 1954: Twenty unidentified flying objects hover through the sky above Florence and fly over the city’s most famous monuments for fifteen minutes. While everyone leans their heads back and stares, no one realizes what’s really happening. The extraterrestrials are contacting someone, Cosimo Rinaldi, a Florentine who is also an expert on the city. From that moment on, he dedicates his life to searching for a meteorite that fell to Earth nine hundred years before; this meteorite is a sacred artifact for the alien visitors. More than fifty years later, Cosimo dies mysteriously. Finding the key to the mystery has now been thrust upon Alfredo, a young man who was a member of Cosimo’s UFO club and had been intrigued by Cosimo’s silence for some time. He is convinced that Florence, as home to the greatest figures of the Renaissance, is a unique, extraordinary city – and that the explanation for this is not entirely rational. Suddenly Alfredo disappears. Where did he end up? Who can complete his search? What did those aliens want back in 1954? Why indeed was Florence the cradle of the Renaissance?
