A strange and some might say warped, erotic drama from director Robert Van Ackeren, Die Reinheit des Herzens is a nearly abstract look at the changes in one woman's inner self. Lisa (Elisabeth Trissenaar) is married to a down-and-out writer who one day forces her into a liaison with a book thief. Lisa works in a bookstore and caught the thief stealing. The result was the unwanted erotic relationship that eventually changes the way Lisa looks at herself and her family. As her husband goes from bad to worse, she starts to reconsider her affair, yet in the end, her husband's alienation and her own responses to her life are nothing the normal family would want to emulate.
