The heretic's daughter

In 1752, Sarah Carrier Chapman writes a letter to her granddaughter revealing a secret she has buried in her heart for over half a century. After Sarah and her family arrived in Andover, they encounter a community stricken by superstition and fear due to Native-American raids and the spread of a plague. Suddenly the Puritans believe that heretics in their town are responsible and the witchcraft trials begin. Sarah's mother Martha is among those who are arrested.
