Last Sin Eater

It's an Appalachian burial tradition that fascinates 10-year-old Cadi. A mysterious man has just "absolved" the sins of her grandmother by eating bread and drinking wine at her gravesite. Consumed with guilt over her own unrighteousness, Cadi seeks the same redemption from this "sin eater"---while she's still alive! Is this man really the absolver of sins?
