Young standard bearer Quintus Tullius, in Britain with the Ninth Roman Legion as part of the empire's efforts to calm mutinous tribes, and on a personal mission to find the bones of his grandfather who died at Stonehenge, falls in love with beautiful Regan, only to learn she is the foster daughter of Boadicea, instigator of the rebellion against Rome.

Boudica, Queen of the Iceni, also referred to as Breaca, leads in her pursuit of the Roman invaders in first-century Celtic England while Ban, Breaca's half brother, has thrown his loyalty to the service of Rome against her.

In A.D. 60, the Ecini tribe restlessly waits for the Celtic queen Boudica to rise up and lead them into victory against Rome, and when she arrives, she fearlessly takes control of the armies and uses her own power to take the country's future into her own hands.
