After burning down the city of Rome, the inhumane tyrant Nero (Charles Lawton Charles Laughton) points the finger at Christians and begins to hunt and kill Christians on a large scale. Not only that, Nero issued a decree to send captured Christians to the arena. Marcus (Frederick March Fredric March), Rome's top military officer, is ordered to kill the captured Christians. Two of the captured Christians were about to escape, and Marcus was going to arrest them, but Marcus couldn't help falling in love when he saw their stepdaughter Messica (Alyssa Randy Elissa Landi). Marcus quickly fell in love with the beautiful Maxika and ordered the release of all Christians. Marcus's move not only infuriated the tyrant Nero, but also made Queen Paya (Claudette Chauchoin Claudette Colbert) who had been secretly in love with him jealous and jealous.
