Having pursued Pompey into Egypt, Caesar arrives in Alexandria and meets the boy king Ptolemy XIII, who offers the general a surprise gift. Vorenus and Pullo play liberators again, freeing Ptolemy's incarcerated sister, Cleopatra. Caesar seeks payment from Egypt for past debts, and ends up forging a strategic union to ensure his legacy.

Cleopatra arrives in Rome to pay her respects to Caesar--and to attempt to get her young son legitimized. The Egyptian Queen's arrival intrigues Mark Antony and rankles Atia, who barely tolerates her new rival and Servilia during a fete. Called off a grisly mission at the last minute, Timon returns home to find his brother Levi has unexpectedly arrived from Jerusalem, his disdain for all things Roman intact. Meanwhile, Erastes' death has plunged the Aventine Collegium, and Rome's river commerce, into chaos. In an effort to restore order, Mark Antony orders Vorenus to assume Erastes' captaincy, and he and Pullo bully the warring gangs into an uneasy truce. Frustrated by Mark Antony in his attempt to secure his inheritance, Octavian takes out a loan to pay off Caesar's promise to the people, angering his mother and especially Mark Antony, who refuses the boy's offer of a power-sharing strategic alliance. The confrontation leads to Octavian leaving Rome.

Rome is facing a dire shortage of grain, forcing Octavian to barter with Mark Antony to get new shipments sent from Egypt. But instead of agreeing to Octavian's price--money and territory--Mark Antony flatly turns him down, pointing towards an inevitable conflict between the two former allies and, perhaps, Vorenus and Pullo. As a last resort, Octavian sends Atia and Octavia to Alexandria, knowing their reception will most likely be a chilly one. At the Collegium, where Pullo is rationing out grain to increasingly restless Romans, Gaia saves her master from a caged animal's wrath, but can't save herself. After fleeing a deteriorating situation in Egypt, Posca gives Octavian the ammunition he needs to turn the people against Mark Antony, setting in motion the wheels of war.

(Series finale.) In the aftermath of the battle of Actium, Mark Antony returns to Alexandria, settling into a world of numbing debauchery with Cleopatra. Meanwhile, Octavian turns to Pullo to try to convince Vorenus to give up Cleopatra's palace in lieu of a fiery siege. Predictably, Vorenus refuses, but Cleopatra seems all too willing to dupe Mark Antony in order to save her life, if not her honor. With Octavian's army at the palace steps, Vorenus flees with Caesarion, Cleopatra's imperious son and Caesar's supposed heir, whom Octavian wants dead. As Vorenus exits the city with the boy, Pullo is ordered by Octavian to track them down. Their journeys lead Vorenus and Pullo back to Rome for an emotional reunion at the Collegium--just as Octavian's triumph is being held amidst bittersweet pomp and circumstance.
