სერიალის მესამე, ფინალური სეზონი, რომელშიც ნაჩვენებია ახალგაზრდა კეისრის ცხოვრება.
The Thracians had been persuaded by Claudius Glaber to serve as auxiliaries in the Roman legions in a campaign against the Getae, who had often plundered Thracian lands.
However after Glaber reneges on the deal and switches his attentions from the Getae to attack Mithridates in Asia Minor, the Thracians feel betrayed and mutiny.
Captured by Glaber, Spartacus is condemned to death as a Gladiator, whilst his wife Sura is condemned to slavery.
Spartacus, however, proves to be a formidable gladiator, and defeats the four gladiators tasked with executing him.
The mighty slave army, led by Spartacus, has crushed all before it, scattering the legions of Rome.
Now invincible, he marches towards the Alps and freedom. Crassus, the richest man in Rome, has raised an army to rival Spartacus, and there are murmurings of rebellion in Spartacus' own army.
Spartacus, on the brink of glory, must make a crucial decision - to go forward over the Alps to freedom, or back to face the might of Rome and try to break its power forever.
It has been nearly one year since the slave rebellion started (which is known as the Third Servile War).
He becomes a favorite of the crowd, leading Senator Albinius to commute his death sentence to a life of slavery.
