Treacherous Roman senator Lucius Quintilius plans a secret journey into Thrace to recover a legendary treasure. He is accompanied by his daughter Livia posing as a Christian slave girl, his cruel henchman Commodio, and Terenzius, an ex-gladiator and Nero look-alike who fools the local Thracians into believing he is the real Emperor. But Lucius's plans are thwarted by Spartacus and his band of rebels who succeed in capturing the treasure for Thrace. When news arrives from Rome that the real Nero has died, local Roman governor Consul Metellus joins forces with Spartacus to defeat the traitors.
Unfortunately the movie Challenge of the Gladiator is not yet available on HBO Max.
