2 part miniseries.

A feminist reimagining of the Arthurian legends from the perspective of the women who wielded power behind King Arthur's throne. Follows the women of Avalon from their childhoods through the ultimate fulfillment of their destinies in the battle between Christianity and Paganism that threatens to bring down the kingdom.

As the story begins, the people of the British Isles fight valiantly against barbarian invasion. Their struggle for survival leaves little time to mend the growing schism between the new Christian faith and the old Pagan religion that has long preserved the kingdom. Viviane, The Lady of the Lake, presides as high priestess on the mist-shrouded Isle of Avalon, the pagan seat of power, and a mystical world invisible to nonbelievers. But as Christianity gains hold over Britain and more people turn away from the Goddess, this mysterious land becomes difficult for even the faithful to reach.

Viviane plans to save Avalon by annointing and training her niece, Morgaine, as her successor, manipulating the royal lineage to produce Arthur, a king who will embrace both pagan beliefs and Christianity, thus saving Avalon. Morgause, Viviane's evil sister endeavors to thwart her plans.
