Maria is a powerful young witch residing in medieval France with her two familiars during the Hundred Years' War against England. As the conflict intensifies and innocents suffer from its devastation, Maria grows weary of the situation and starts employing her magic to hinder further hostilities, hoping to preserve peace. However, her persistent interference soon draws the attention of the heavens, prompting the archangel Michael to be dispatched to stop her from meddling in human affairs. The divine entity confronts Maria, forbidding her from using her powers and decreeing that her magic will be stripped away if she loses her virginity. Despite being branded a heretic, Maria steadfastly ignores Michael's warning and continues to disrupt the war between the two nations. Yet, as the Church begins plotting to seize the witch's power and permanently halt Maria's interference, her efforts to make peace may soon reach their end.
