IMDb Wikipedia

Rock Stevens is Spartacus, who has superhuman strength and is really more like Hercules than Spartacus. There is a cumbersome plot about Nero, or Nero's fake, and a treasure that will free the slaves from their Roman persecutors. A girl gets in the way and there are some vague references to Christianity. The torture and gladiator scenes are weak, so this turns into a boring soap opera set in what was once Thracia but today southeast Europe.
