When Roman generals Pompey and Crassus lead their mighty legions of soldiers and mercenaries into the lands surrounding Italy, neither could anticipate the turmoil caused by one bold mercenary: Spartacus. A Thracian warrior, Spartacus deserts the Roman army, but is captured and made a slave, forced to fight as a gladiator. But in 73 BC the untamable barbarian leads a slave revolt of 70,000 gladiators against the Roman Republic. Though the brutal and conniving Roman General Crassus is finally able to suppress the revolt, his rival, the more popular Pompey, takes all the credit, sparking a division within the Republic itself that will ultimately spell its demise.
