Lucius Vorenus, the power-hungry "Son of Hades", controls the Aventine but practices a pointless, beastly reign of terror, coming down hard on gang captains for futilities, and nearly ruins his friendship with Pullo, whose efforts to calm things down are mistaken for disrespect and disobedience, even starts a fight once he learns the truth about Niobe; Pullio leaves Rome disgusted. After Atia convinces Marc Antony the governorship of ghastly Macedonia after his consulate would not only be unpleasant but leave him exposed to his dangerous enemies, he puts the heat on senatorial leader Cicero to give him Gaul instead, which once was the base for Julius Caesar's coup d'état. The slave Duro endures male prostitution but most arrogantly demands extra pay and even a kiss from Servilia as it will take more time to commit the planned murder in Atia's home. Marc promises Atia not to hurt Octavian, whose recruiting he calls a joke, after putting down his party's expected plot. Brutus has a hard time controlling himself while soliciting the Bithynian king's financial support to raise an army. Instead of proposing Antony for governor of Gaul, Cicero sends an extremely insulting speech and joins Octavian's growing army.

Having learned that Vorenus' children are alive, Pullo sets off to find him in Gaul where he is again a serving soldier in Mark Antony's army. He had hoped to arrive before Octavian and Antony's armies meet in battle. Too late however, he is forced to find what is left of Antony's army in the mountains. He finds Vorenus alive and well, if somewhat battle worn, and they set off to find the children. The victorious Octavian plans his return to Rome. In Western Turkey, Brutus and Cassius amass their own army, now 9 Legions strong. In Rome, Servilia's attempt to kill Atia fails and Atia has her kidnapped tortured beyond what even her henchman Timon can stand.
