The tragedy opens in Alexandria, where Mark Antony neglects his imperial duties in Rome to indulge in an extravagant romance with Cleopatra, Queen of Egypt. Receiving urgent news of political unrest and the death of his wife Fulvia, Antony tears himself away from his mistress to stabilize the Roman empire. In Rome, a fragile truce is forged between Antony and Octavius Caesar, sealed through Antony's marriage to Caesar's sister, Octavia. This political union fails to keep Antony from his true desire, and he soon returns to Cleopatra, abandoning his wife and alienating Caesar entirely.
Furious at the insult to his sister and the division of imperial territories, Caesar declares war against Egypt. Despite the sound strategic advice of his commanders, Antony insists on fighting Caesar by sea, a disastrous error fueled by pride and Cleopatra's insistence on participating. During the crucial battle at Actium, Cleopatra’s squadron suddenly flees the fight, and Antony shamefully abandons his fleet to follow her, plunging his army into chaos and irreversible defeat.
As Caesar's forces close in on Alexandria, Antony suffers further betrayal when his remaining followers and fleets desert him. Blaming Cleopatra for his ruin, a furious Antony threatens her life, driving the queen to take refuge in her monument and falsely report her own suicide. Overcome with grief upon hearing of her death, Antony attempts to fall upon his sword, only to discover she still lives just in time to die in her arms.
Captured by Caesar, Cleopatra resolves to avoid the humiliation of being paraded as a captive through the streets of Rome. Dressed in her royal robes and employing a venomous asp smuggled in a basket of figs, she takes her own life to join her lover in death. The tragedy concludes with Caesar ordering their joint burial, acknowledging the monumental scale of their passion and the enduring sorrow of their ruin.
