It has been five years since Constantine was proclaimed Augustus by his father's legions in Britannia. Now he is locked in a savage war with Maxentius, son of Maximian. After a series of hard-fought battles in northern Italia, Constantine is marching on Roma, the ancient capital of the empire. Constantine is given a vision in his dreams. He sees a strange symbol and hears a voice telling him that it is a sign of victory and triumph. It is the Chi-Rho, used by Christians to secretly identify themselves to one another. Christianity has been proscribed since the days of the Emperor Diocletian and many thousands of Christians have been brutally tortured and executed without mercy. Nevertheless, Constantine instructs his soldiers to paint the prohibited symbol on the fronts of their shields as a mark of invincibility. Fourteen legions march toward Roma, proudly bearing the Chi-Rho emblazoned shields. Constantine's army meets the enemy at the Milvian Bridge, just outside the city. The fate of the empire hangs in the balance. The course of history is about to change.
