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.

Things pick up shortly after Caesar's murder. Octavian wants to keep his family from fleeing the city so he devises a plan. News of this makes Antony happy so he tells Brutus. Vorenus mourns Niobe's death but casts aspersions upon his children.

Brutus and Cassius struggle to raise foreign armies to oppose the Cesarean party. Mark Antony's plans to change his post-consul proconsular governorship from Macedonia to Gaul are derailed when Cicero delivers an in-absentia message to the Senate, and throws his support behind Octavian. Vorenus struggles to contain an all-out gang war in the Aventine Collegium, of his own making, that he blames on Pullo. In the house of the Julii, Octavia passes the hours in a drug induced daze, while a duplicitous youth named Duro, planted amongst the Julii by Servilia, looks for the chance to set a deadly plan in motion.

Pullo races to find Vorenus with news of his family's fate. Servilia's plans to eliminate a rival exact a high price from her. Cicero is astonished when Octavian sends word that his victorious legions are coming home to Rome. In Rome, Timon finally grows weary of Atia's bidding.

Despite Pullo's advice, Vorenus and his family return to the Collegium with his family who is reunited, and cleansed of their ordeal. Octavian is denied a triumph and urges Cicero to endorse his bid to be made Consul in exchange for an agreement to allow Cicero to veto his actions. Octavian takes both Cicero and the Senate by surprise with his first Consular act. Vorenus attempts' to make peace with Memmio and Cotta create suspicions that he has gone soft.
