With Scipio and Cato defeated, Caesar returns home to a hero's welcome. Vorenus and Pullo's showdown with local thug Erastes gets an unexpected reprieve from Caesar. Servilia's plan to use Octavia to unearth a secret about Caesar backfires.

Unanimously proclaimed Dictator by the Senate, Caesar pronounces the war over, and prepares for five days of feasting and games honoring his "triumph." No longer an enlisted soldier, Pullo eyes a pastoral future with Eirene, while Vorenus runs for municipal magistrate, with Posca's help. Meanwhile, Octavian retrieves Octavia from her self-imposed exile. And Servilia invites a revenge-minded Quintus Pompey into her home, to Brutus' dismay.

Vorenus sees to it that veteran soldiers receives severance on behalf of Caesar, and is then invited along with Niobe to one of Atia's parties.
