While Rome celebrates the peace and greatness of Augustus, Titus, the son of Alix, is kidnapped and forced to fight in clandestine games organized by masked aristocrats. He is seriously wounded and survives thanks to the intervention of Livie. Alix infiltrates the bottoms to find the guilty and discovers that these shows are taking place in a secret theatre belonging to Mécène. Livie makes the responsible ones arrested but the savings to better control them. Mécène, the main culprit, is condemned to a discreet death by the poison. The scandal is stifled, and the imperial order is preserved.
