Caesar's fevered pursuit of Pompey takes him to Egypt, where he makes a terrible discovery. Determined to establish supremacy over the Egyptian court, he sends Pullo and Vorenus off in pursuit of a fugitive Cleopatra.

Proclaimed Emperor by the Senate, Caesar pronounces the war over, and prepares for five days of feasting and games. No longer an enlisted soldier, Pullo eyes a pastoral future with Eirene; Vorenus runs for municipal magistrate, with Posca's help; Octavian retrieves Octavia from her exile; and Servilia invites Quintus Pompey into her home, to Brutus's dismay.
