Pharsalus in 48 BC, Julius Caesar goes to Egypt, under the pretext of being named the executor of the will of the father of the young Pharaoh Ptolemy XIII and his sister Cleopatra. Ptolemy and Cleopatra are in the midst of a civil war of their own and she has been driven out of the city of Alexandria. Ptolemy rules alone under the care of his three "guardians", the chief eunuch Pothinus, his tutor Theodotus and General Achillas. Cleopatra convinces Caesar to restore her throne from her younger brother. Caesar, in effective control of the kingdom, sentences Pothinus to death for arranging an assassination attempt on Cleopatra, and banishes Ptolemy to the eastern desert, where he and his outnumbered army would face certain death against Mithridates.

After refusing several times to leave Egypt, Cleopatra acquiesces and meets him on her royal barge in Tarsus. The two begin a love affair, and Cleopatra assures Antony that he is much more than a pale reflection of Caesar. Octavian's removal of Lepidus forces Antony to return to Rome, where he marries Octavian's sister Octavia to prevent political conflict. This upsets and enrages Cleopatra. Antony and Cleopatra reconcile and marry, with Antony divorcing Octavia. Octavian, incensed, reads Antony's will to the Roman senate, revealing that Antony wishes to
