Sicily, 412 BC: the infinite duel between a man and a superpower begins. The man is Dionysius, who has just made himself Tyrant of Syracuse. The superpower is Carthage, mercantile megalopolis and mistress of the seas. Dionysius, twenty years old and a fearless combatant of the army of Syracuse, is forced to witness the horrifying massacre of Selinus - a splendid Greek city on the edge of the Carthaginian provinces - which he attributes to the fatal indecision of the democratic government. From that moment, a rage is born within this young man that will change the course of history. Dionysius dreams of transforming Sicily into a Greek island. To achieve total control over the economic and military resources of his city he is willing to condemn himself in the eyes of history for centuries to come: to be eternally branded as the Tyrant. Thus begins the adventure of a man who built the largest army in antiquity and invented dreadful war machines; the adventure of a man who was also a dramatist, a statesman, a poet and a lover, tied for all his life to the memory of his unfortunate first love.
