Antonius returns to Alexandria following his victory in Armenia. Cleopatra meets him at the harbor holding their two-year-old son, Ptolemy Philadelphus. Antonius has brought the Armenian royal family as prisoners in gold chains and announces they will hold a triumph in Alexandria.

During the grand procession, Cleopatra and Antonius ride a chariot dressed as Isis and Dionysus. At the gymnasium, thrones have been erected for the family. When Cleopatra sits on her golden throne, she discovers live asps caged within the armrests—a gift from Antonius that both startles and pleases her.

Antonius addresses the crowd, declaring Cleopatra the Queen of Kings and publicly granting kingdoms to their children: Ptolemy receives Syria, Cilicia, and Phoenicia; Helios receives Armenia and Media; Selene receives Cyrene. He then proclaims Caesarion the true son of Julius Caesar and claims Rome in his name.

Amid the celebration, Cleopatra spots a man wearing a Roman army belt. The assassin draws a knife and rushes toward Caesarion. Antonius intervenes, but the man wounds Caesarion’s arm before being subdued. Cleopatra stitches her son’s injury and interrogates the assassin, who admits he acts on Octavian’s authority and calls Caesarion illegitimate.

Cleopatra orders the asps from her throne brought forward and releases them onto the assassin’s bloodied stomach. A juvenile cobra bites him, paralyzing him with venom, before slithering away. At her command, Antonius kills the paralyzed man.

Later, Cleopatra argues with Antonius about the threat Octavian poses. To reassure her, Antonius formalizes his will, assigning his conquered territories to their children, with seven scribes to witness and seal the document.

Octavian declares war on Cleopatra. Faunus returns from Rome beaten and robbed—Octavian’s men have stolen Antonius’s will and illegally read it before the Senate, embellishing it with inflammatory claims. Rome declares Cleopatra an enemy of the state.

Cleopatra and Antonius assemble a massive fleet and army and establish their base in Patrae, Greece. They debate strategy constantly—Antonius wants an aggressive strike while Cleopatra favors defensive positioning. They compromise and move their fleet to Actium, where conditions prove miserable: swampy terrain, biting insects, and low morale. Cleopatra’s dread deepens when swallows nest on her ship, a bad omen. They send their children back to Alexandria with Charmion.

General Dellius brings news that Octavian has taken Methone, cutting their supply lines. At a war council, they devise a plan to lure Octavian onto land, but Dellius defects to Octavian with their strategy. Desertions increase as food dwindles. Cleopatra realizes they must retreat before starvation claims them.

She devises a desperate plan: Sacrifice 30 minimally crewed ships in a diversionary attack to open a gap in Octavian’s blockade for the rest of the fleet to escape. They host a lavish final feast for the 30 commanders, who do not know they are being sent to their deaths. Cleopatra is consumed by guilt.

At dawn, she and Antonius exchange tearful farewells. He gives her his wooden Dionysus figurine; she gives him her ivory dagger necklace. The diversionary attack begins. Cleopatra watches her ships burn as they ram the Roman fleet. After 10 ships from each side are destroyed, a gap opens, and she leads the surviving fleet through the blockade, her eyes fixed on Egypt.

Cleopatra’s fleet arrives in Alexandria, where her children and Charmion greet her. Caesarion immediately convenes a war council to prepare the city’s defenses. Cleopatra makes Charmion promise to take the children through the palace tunnels and escape if the city falls.

Days pass with no word from Antonius. When Charmion reports that Octavian’s fleet of 500 ships is on the horizon, Cleopatra’s dread gives way to calm acceptance. She vows she will not be led in triumph through Rome.

She says farewell to each of her children and to Charmion, then instructs Faunus to tell Octavian she has already died in the Temple of Isis, creating a diversion so the children can escape. She locks herself in the temple in her finest regalia and writes a final message to Antonius on an obsidian slate, sending it with her maid, Eiras. She prepares a poisoned wolfsbane tincture.

As she is about to drink it, she hears Antonius’s voice. She unbars the door to find him dying on the temple steps—having received her message, he stabbed himself with the ivory dagger she had given him. She pulls him inside and holds him as he dies. His army was only half a day away. His last words assure her their children are safe with Charmion.

Cleopatra grieves and prepares to use the poison when Charmion appears, having entered through a tunnel connected to the temple. Charmion reveals she could not keep her promise to leave and will die with Cleopatra. Cleopatra accepts her decision. She laces two golden hairpins with wolfsbane. Charmion presses the pins into her own arm and collapses. Cleopatra lies down beside Antonius and Charmion, says a final farewell, and pushes the poisoned hairpins into her own skin. They die together.

Cleopatra awakens in a crimson realm and is greeted by the goddess Isis, who reveals that Cleopatra is not permitted to pass into the afterlife. The Ptolemaic dynasty’s divine powers were never gifts but a curse—punishment for their ancestor Ptolemy I Sōter, who desecrated ancient tombs while searching for forbidden knowledge. Each Ptolemy’s power was designed to bring about their ruin, but children born of true love are born free of the curse, which is why none of Cleopatra’s children were marked. Cleopatra’s specific curse is resurrection: She can never truly die and will return to the same body each time. Isis pushes her back into the mortal world.

Cleopatra awakens in the temple beside the bodies of Charmion and Antonius, devastated to be alive while they are dead. Hearing Octavian’s soldiers approaching, she stages a final deception: She wraps her royal cloak around Charmion’s body, lines the corpse’s eyes with ash, and places her crown on Charmion’s head so she will be mistaken for Cleopatra.

Cleopatra escapes through the temple’s tunnels and reaches the seaside cave where her four children wait, having been led there by Charmion before she returned to the temple. Mistaken for a servant rather than the queen, she and the children escape by boat while Octavian’s men search for Cleopatra.

Cleopatra reveals she has died and been reborn many times across thousands of years. Her children’s fates varied: Caesarion was captured and executed by Octavian; Selene and Helios were captured and raised by Octavia. Cleopatra and her youngest son, Ptolemy, found sanctuary on an island they named the Land of Punt, living simply. When she eventually dies of old age and is reborn in her younger body, Ptolemy is 57.

Years later, Cleopatra learns of a newly crowned queen in Mauretania. She sails there with Ptolemy and discovers it is Selene, with Helios among her courtiers. Fearing the consequences of revealing herself, Cleopatra returns to her island without making contact. She later learns both Selene and Helios died of a sudden illness.

After all her children are gone, Cleopatra spends years dying repeatedly—by blade, drowning, fire, and poison—always returning to her body. Eventually she learns to live with curiosity and reflection, traveling the world, mastering 25 languages, and studying in libraries and universities.

She reflects on seeing her story distorted across centuries through plays, films, paintings, and books. Addressing the reader directly, she declares she is part of every woman’s experience and cannot be reduced to simple labels.
