Harrison Ford stars as John Book, the police detective investigating the murder. When Book discovers that the crime was part of a conspiracy involving several officials in his department, he flees Philadelphia to the Amish community where Samuel lives with his widowed mother, Rachel (Kelly McGillis). Slowly assimilating himself into the Amish community, Book eventually finds himself falling in love with Rachel in the midst of his investigation. Eventually, the corrupt police track Book down, and he is forced to confront them, while also trying to protect Rachel and Samuel. ~ Matthew Tobey, Rovi
