The Dancing Plague tells a true story, from 1518, when hundreds of inhabitants of Strasbourg were suddenly seized by the strange and unstoppable compulsion to dance, from the imagined perspective of Mary, one of its witnesses. Prone to mystic visions as a child, betrayed in the convent to which she flees, then abused by her loutish husband, Mary endures her life as an oppressed and ultimately scapegoated woman with courage, strength, and inspiring beauty.
