Hosted by Gregg Wallace, a show in which ordinary members of the public go toe to toe with the greatest generals, as they refight some of the most significant battles from history in an innovative mix of genuine history and game show competition. June of the year 451, and the forces of the crumbling Roman Empire are battling the whirlwind military might of the Huns in a field in France. Can the Barbarian hoard bring the Roman Empire to its knees once and for all, or will the mighty Roman military machine put an end to their invasion? This time, a team of karate veterans take on the role of defending the Roman Empire against attack by Attila and his Hunnish hordes. Can they stop a team of kickboxers from rewriting history and over running Europe? Will the legendary horsemen of Attila or the Roman military machine emerge victorious?
