This stylish mix of documentary and historical epic chronicles the reign of Commodus, the emperor whose rule marked the beginning of Rome's fall. In the first episode, the death of Marcus Aurelius brings a century of Roman triumphs and victories to an end, transferring power to his spoiled, unprepared son Commodus. When his father bequeaths him the world's mightiest empire, he is forced to spill the blood of both friends and enemies alike to keep his crown.
In the second episode of the series, the Germanic tribes strike as Marcus Aurelius succumbs to disease, leaving a skeptical Emperor Commodus to prosecute a war that doesn't interest him.
In the third episode of the series, Commodus rises to power as Rome's new emperor, but not everyone supports his ascent. Among those conspiring against him: his older sister Lucilla.
In the fourth episode of the series, Commodus defeats his sister's coup but withdraws from governing, allowing others to amass power while he engages in an affair and banishes his wife.
In the fifth episode of the series, lavish imperial games at the Colosseum are highlighted by the emperor's bloody victories, but his paranoid abuses of power lead to a final betrayal.
