Set in the seventeenth century, this is the story of Anna, a young wife who is revolted when her husband, an elderly pastor, has an old woman burned at the stake as a witch. She tells her husband that she and his son are in love and that she wishes him dead. The pastor then dies of a stroke and Anna is accused of killing him by witchcraft. Deserted by the cowardly son and reviled by the pastor's shrewish mother, Anna is offered an opportunity to take the oath swearing she did not kill her husband. She seems to become what she is accused of being and in a strange ending refuses to take the oath.
