After the bloody escape from the House of Batiatus that concluded Spartacus: Blood and Sand, the gladiator rebellion begins to strike fear into the heart of the Roman Republic in Spartacus: Vengeance. Praetor Gaius Claudius Glaber and his Roman troops are sent first to Capua, and thence to Mount Vesuvius, to crush the ever-growing band of freed slaves under Spartacus before they can inflict further damage. Spartacus finally comes face to face with the man who sold his wife into slavery and condemned Spartacus to slavery as a gladiator owned by Batiatus. But Glaber fails in his obsession with killing Spartacus. The freed gladiator champion Gannicus decides to join ranks with the rebels under Spartacus. And the widows of both Lentulus Batiatus and Gaius Claudius Glaber are soon to join their dearest husbands in the afterlife.
