In 1930s Britain, a savage, civil war between two royal families has just concluded. But even as the newly installed King Edward (John Wood) takes the reins of power, his ruthless, younger brother Richard (Ian McKellen) sets in motion a monstrous scheme to claim the crown for himself. Enlisting the aid of equally duplicitous allies in the court, Richard embarks on a merciless, single-minded campaign of betrayal, seduction and cold-blooded murder to achieve the goal that has obsessed him all of his tortured life: to be king...at any price.
