Belladonna of Sadness

Jeanne and Jean are newlyweds in a rural village in France during the Medieval Period. Their idyll is shattered when Jeanne, on her wedding night, is raped in a ritual deflowering by the local baron and his courtiers. She is granted considerable magical powers, and returns to find the village has been infected with the bubonic plague. She uses her powers to create a cure for the disease and wins the villagers' favor with her magic, presiding over orgiastic rites among the villagers.
