Nero comes to power in Rome through his mother Agrippina's relentless maneuvering, which includes securing his adoption by Emperor Claudius and clearing the path to succession by any means available. The film follows his fourteen-year reign through historian interviews and reenactments, tracing how a young emperor initially popular with the public curdles into a ruler who has his own mother and stepbrother killed to protect his position. It covers the fire of AD 64, the legend of Nero fiddling while Rome burned, and his use of Christians as scapegoats for the disaster, an early instance of state-organized persecution. Reenactments stage the palace intrigue and executions rather than leaving them as narration, while experts weigh how much of Nero's reputation for depravity was contemporary record versus later smear campaigns by Rome's historians. The film closes on his suicide in AD 68, presenting a reign that left the treasury drained and the empire's political stability shaken well after his death.
