18-year-old Germanic princess, Cassius, witnessed the destruction of her village by the Romans. Now, she is being made to serve a Roman Senator as his slave. During the Battle of Teutoburg Forest in nine A.D., Cassius is forcefully abducted again but this time by an unknown soldier, named Sgt. Banks. Banks tells her that she is the key to his mission, which is to stop the death of millions. And even though Banks has the build and abilities of a Roman soldier, he is not a centurion. In fact, he is not a soldier of her time at all. Neither Banks nor Cassius foresees that the stress from their journey has the potential of bringing out their previously contained inner demons, but it does. And when they are tested the most, their newfound feelings for each other could be their undoing and mankind's as well.
