Atia and her family have stayed behind when Pompey and others fled and she now throws a party for her triumphant uncle, Julius Caesar. She clearly has her sights set on the great leader and is puzzled when he sends her a guest list that includes Servilia of the Junii. She soon finds out why. Pompey wants to find out what happened to the gold from the Roman Treasury and sends his son Quintus to Rome to find out what happened. They go directly to Vorenus' home but he has no idea what they are talking about. Pullo arrives however and Vorenus tells him to go directly to Caesar himself and explain. Octavian meanwhile learns of one of his uncle's secrets.

Caesar contemplates Pompey's counteroffer. Vorenus continues to struggle as a businessman and must reevaluate his career choice. Atia schemes to come between Caesar and Servilia and Pullo seeks Octavian's help.

The price of Caesar's mercy: Cicero nominates Caesar to an unprecedented ten-year dictatorship and Brutus speaks in support of the motion. With martial authority and Niobe at his side, Vorenus campaigns for magistrate under Posca's advice, but is shocked to learn from Posca that Caesar has already fixed the election in Vorenus's favor. Meanwhile, Atia continues her humiliation of Servilia while denying any involvement in her assault. But Atia becomes troubled by the silent depression of Octavia after Octavian compels her to return home from the cloister where she had fled. As Servilia lies at home shattered by her recent attack, she soon revives and gets her self-confidence back when she takes in the homeless and embittered Quintus Pompey whom she sees as her tool for revenge against Caeser for leaving her. As Caesar prepares for his Triumph involving five days of celebration and games, Antony finds that the dictator has no sense of humor about the trappings of power. The circulation of a denunciation of Caesar, signed by Brutus, fascinates Rome but stuns Brutus, who suspects his mother. Denied permission to march with the Thirteenth in the Triumph, the dejected Pullo resolves to make a new life as a civilian with Eirene, but his dream leads only to horror for the Vorenii and utter wretchedness for himself.

Vorenus' defense of Caesar lands him in an unexpected position of power within Rome. Meanwhile, Servilia hurls the final obstacle in her ambitious and complex revenge plan against Atia.

In the wake of Caesar's death, Mark Antony considers a move north, while Vorenus issues a curse he soon regrets.
