Cleopatra, the famed Egyptian Queen born in 69 B.C., is shown to have been brought by Roman ruler Julius Caesar at age 18. Caesar becomes sexually obsessed by the 18 year old queen, beds her, and eventually has a son by her. However, his Roman followers and his wife are not pleased by the union. In fact, as Caesar has only a daughter by his wife, he had picked Octavian as his successor. The out-of-wedlock son of Cleopatra is seen to be a threat to his future leadership. Thus Brutus and other Roman legislators plot the assassination of Caesar. Caesar's loyal general, Marc Antony, and Octavian then divide up the Roman empire. Antony takes Egypt and soon takes up the affair with Cleopatra.
