Spartacus, a prisoner of war from Tracia, was made a slave at a Roman stone quarry. A rich merchant, Alvinius, is attracted to Spartacus' combination of fighting spirit and tactfulness. He sends Spartacus to a martial arts academy. Spartacus becomes a formidable gladiator. One day, Savinius, the Roman Governor, visits the school. To entertain the important guest, a bout is held which puts Spartacus up against a renowned swordsman, Gaza. Gaza is defeated. It is then discovered that Spartacus is no ordinary prisoner of war but the best warrior in the whole Tracian Army.
