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 Claudius Glaber and his Roman troops are sent to Capua to crush Spartacus' growing band of freed slaves before they can inflict further damage. But 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 falls in the attempt of killing Spartacus. Former champion and God of the Arena Gannicus returns to fight Spartacus, only to join and aid Spartacus as he takes on the Roman Republic, lead by Marcus Crassus. Spartacus is given a choice between satisfying his personal need for vengeance against the man who condemned his wife to slavery and eventual death, or making the larger sacrifices necessary to keep his budding army from breaking apart.
