Jerusalem and the Sinai desert, first century AD. In the turbulent aftermath of the crucifixion of Jesus, officers of the Roman Empire acquire intelligence of a pilgrim bearing an incendiary letter from a religious fanatic to insurrectionists in Corinth. The content of this letter could bring down the empire. The Romans hire a former legionary, the solitary man-at-arms, Telamon of Arcadia, to intercept the letter and capture its courier. Telamon operates by a dark code all his own, with no room for noble causes or lofty beliefs. But once he overtakes the courier, something happens that neither he nor the empire could have predicted.
