A dream-like version of the Sabbath in the Middle Ages: one night at full moon, the women leave home to meet with the devil in the woods. Several orgiastic ceremonies later, they all return home at cockcrow. All except for one, the youngest, who is under an evil spell.

A young "social investigator" meets a bohemian Englishman who decides to move in with her, disrupting her daily life and challenging her lifestyle and values.
