The govern of Constantinople together with Senator Nestor send the warrior Mira to help the loyal commander Aurelius to rescue Romulus with a few soldiers that have survived the attack and bring him to Constantinople. They succeed in their mission but when they return, they discover that they have been betrayed by Nestor. Without any other alternative, they navigate to Britannia to meet the last Roman legion, but they have a huge surprise.
