Dr. Vikström, a scholar of Kabbalah, mysticism, symbology, and dead languages, discovers the lost tome of the "Edda" written by the Icelandic poet and historian Snorri Sturluson. This book not only contains a prophecy about Ragnarok and the awakening of Fenrir, Loki's son, destined to kill Odin, but also how to stop the end of the world. The only way is to discover a man whose future is completely unknown. The chosen one must compose a mystical music and play it on the Organ of Eternity, hidden somewhere in Turin. The magical city par excellence witnesses a race against time, in which eight characters cross paths.
