The arrival of Roman invaders in Britannia forces a tribal queen to navigate a treacherous landscape of political betrayal and personal desire, while a modern-day historian finds her own life unraveling under the weight of the past. As Cartimandua struggles to maintain her sovereignty over the Brigantes tribe against encroaching imperial forces, her internal conflicts mirror the external threats posed by her enemies. Simultaneously, Viv Lloyd Rees, a contemporary historian, becomes increasingly consumed by visions of the ancient queen, leading her to uncover a cursed artifact that bridges the centuries. The narrative oscillates between these two timelines, utilizing a dual-perspective framework to explore how historical trauma and unresolved passions echo through time. Viv must confront the reality of her visions before the dangerous legacy of the past destroys her present.
