In 17th-century France, Father Grandier (Oliver Reed) is a priest whose unorthodox views on sex and religion influence a passionate following of nuns, including the sexually obsessed Sister Jeanne (Vanessa Redgrave). When the power-hungry Cardinal Richelieu (Christopher Logue) realizes he must eliminate Grandier to gain control of France, Richelieu portrays Grandier as a satanist and spearheads a public outcry to destroy the once-loved priest's reputation.
