FBI agent Sally Russwell is sent to investigate a presumed hate crime in a small Amish community in Iowa after three barns are burnt down. Given a rather cool welcome by the locals when she arrives at the crime scene Sally is able to gain the confidence of Amish widow Annie Beiler. A shaky but solid bond is formed between the two women which enables Sally to go on with her investigation. Slowly, Sally starts to learn more about Amish customs. She suspects an Amishman is behind the arson and asks to stay with Annie s family to get a deeper insight into the community. This results in Sally's discovering that Annie's daughter is seeing a young man whose father is being shunned for having built a barn not according to Amish rules.
