Angel or devil, good or evil, Christ or Satan: These are the mystical questions revolving around the nameless figure living in the coastal dunes outside of a small French town. This mysterious drifter begins to touch the lives of a group of women in the village, including a single mother caring for her sick daughter, a hitchhiker passing through en route to Boulogne, and, most vividly, a teenage girl living in an abusive household. The stranger and the girl form a special bond as he saves her from her dilemma and she wanders through dunes and marshes with him, witnessing his unusual acts of wonder and questioning his role in her life.
