Spartacus is a rebellious slave purchased by Lentulus, owner of a school for gladiators. For the entertainment of corrupt Roman senator Marcus Licinius Crassus, Batiatus' gladiators are to stage a fight to the death. On the night before the event, the enslaved trainees are "rewarded" with female companionship. Spartacus' companion for the evening is Varinia, a slave from Brittania. When Spartacus later learns that Varinia has been sold to Crassus, he leads 78 fellow gladiators in revolt.
