In this retelling of real-life events from 1828, Iceland, when Agnes Magnusdottir and two others are convicted and sentenced to death in a brutal double murder thought to have been motivated by greed and jealousy, Agnes is sent to an isolated farm to await execution. Horrified at the prospect of housing a convicted murderer, the family at first avoids Agnes. Only Tóti, a priest Agnes has mysteriously chosen to be her spiritual guardian, seeks to understand her. But as Agnes's death looms, the farmer's wife and their daughters learn there is another side to the sensational story they've heard.
