Plot.
Emperor Tiberius is warned of the threat posed by the Germanic tribes revolting in the northern province of Pannonia. Tribune Marcus Vinditius is entrusted with the insignia of the 7th Legion and ordered by Governor Messala to subdue the rebellion. Magdus, the aging leader of the Pannonian tribes, is angry with Batone because he has compromised the peace terms with Rome, but Batone is a much younger warrior who has lost his reason and lusts for blood.
