In Rome, 216 BC, Fulvius is a murderer, a thief, and condemned to die. Saved by the catastrophic defeat of the Roman Army at the hands of the Carthaginian General Hannibal at nearby Cannae, he's forced into the legion and an altogether unfamiliar world of soldierly duty and honor. Realizing promotion as the unexpected reward for paralyzing fear, Fulvius finds the Army not so dissimilar to the shadowy Roman underworld he knows so well and schemes to make the experience worth his while. He betrays, and is in turn betrayed, in a whirlwind cycle of threat, violence, and criminality leading to an ultimate showdown and reckoning that could undermine the entire war effort. Hannibal is no doubt coming, but that may be the least of Rome's troubles.
