Rome, 46 BC. Caesar prepares four triumphs celebrating victories in Gaul, Egypt, Pontus and Africa. Cleopatra is present in the city, Vercingetorix awaits execution and political opponents must decide whether Caesar’s clemency can be trusted.
Calpurnia fears that someone intends to kill her husband and asks Gordianus to investigate. Amid processions, prisoners and rival factions, he searches for a possible assassin while questioning whether the threat is genuine, manipulated or an unavoidable consequence of Caesar’s new dominance.
