Movie set among the Amish *NOT* Witness
I think it was a made for TV movie where a female police detective or sheriff needs to stay with an Amish family while some crime is investigated and slowly she begins to understand their lifestyle. I originally thought the lead was played by Kate Mulgrew; but I didn’t see anything in her filmography that seemed to match. I remember there was a subplot about one of the local families who were being shunned because they built their barn with a different kind of roof (one that provided more storage space); and the cop eventually understands that the issue isn’t the barn but their pride in doing things differently.
