Purity tells the story of a subtle female rebellion within the religious world, expressed through the personal viewpoint of the director Anat Zuria and three of her friends. Their openness to the camera breaks a profound taboo of silence rooted in two thousand-year-old laws and contemporary social pressures and provides a rare and special look into the world of Jewish religious married life and sexuality while illuminting a hidden path of struggle for religious women in the framework of strict, patriarchal religious law.
