 Spartacus, a Thracian slave, refuses to allow himself to become the animal the Roman civilization would have him be. His love for Varinia, a slave girl, coupled with his revulsion at the crushing treatment and callous murders of his fellow slaves, ignite in his breast a passion for freedom. They escape and are joined by more runaways, and swell to become a vast army. Contrasted with their impassioned plans for open rebellion are the cool, calculating minds of their Roman adversaries Crassus, Grachus and Batiatus. To Rome, a poorly equipped army of slaves are no more threatening than the invasion of insects which attack the city during the hot, humid seasons. The slaves  cries for freedom and their challenge will be but a more diversion from the musty affairs of state. And so, in a chilling engagement, the superior military might of Rome proceeds to crush the army of Spartacus.
