On arriving at a rural monastery, the monk Ambrosius meets a young girl, Benedicta. She is shunned by the local community for being the daughter of the local hangman, but Ambrosius is drawn into a dangerous sympathy with her, and in defiance of the community and his superiors, he starts spending time alone with her. But when her virtue is corrupted by an impetuous young man, the stage is set for a battle between heart, mind, body, spirit, the sins of the past and redemption.
