Rome has now been changed to a modern African country where,amid much song and festivity,Julius Casar accepts the ruler's crown,although a sooth-sayer warns him to beware the Ides of March. Embittered ex-colleague Cassius,envious of Caesar's new status,enlists the support of a group of conspirators,including the previously loyal Brutus,and they kill Caesar, whose adopted son Octavius and friend Mark Antony obtain revenge on the murderers.
