Morgane et ses nymphes (1971)

Driving in their car through France one summer, two young girls – Anna and Francoise – find themselves prisoners of the mythic Morgana, Queen of Witches. Ever since Merlin taught her his secrets centuries before, Morgana has gone on living by capturing the souls of young women, lured to her castle by Gurth, her faithful but jealous slave. All women who agree to give their soul to Morgana are offered eternal youth and beauty; those who refuse her grow old and ugly in the dungeons of her castle. Anna succumbs to the witches’ offer. Francoise, with the help of Gurth, tries to fight back. But, as the eve of the Great Love Feast approaches, she begins to wonder if there is any way to beat the supreme power of the magical Morgana.
