A sheltered Amish child is the sole witness of a brutal murder in a restroom at a Philadelphia train station, and he must be protected. The assignment falls to a taciturn detective who goes undercover in a Pennsylvania Dutch community. On the farm, he slowly assimilates despite his urban grit, and forges a romantic bond with the child's beautiful mother.

In 1850 Oregon, when a backwoodsman brings a wife home to his farm, his six brothers decide that they want to get married too.
