The story of the adventures, in the twilight of the eighteenth century, of a singular couple formed by a little orphan with mysterious origins and his young Italian nurse of a similarly uncertain birth. They lead us in their wake, from Rome to Paris, from Lisbon to London, from Parma to Venice. Always followed in the shadows, for obscure reasons, by a suspicious-looking Calabrian and a troubling cardinal, they make us explore the dark intrigues of the Vatican, the pangs of a fatal passion, a gruesome duel, banter at the court of Versailles and the convulsions of the French Revolution.

Aram, a young man from Marseille of Armenian origin, blows up the Turkish ambassador's car in Paris. Gilles, a young cyclist who was passing at that precise moment, is seriously injured. Aram's mother feels guilty and feels the need to visit Gilles at the hospital and beg for his forgiveness, something that Gilles does not understand. Against the advice of his comrades in Beirut, Aram decides to go meet his victim.
