The tension of the film involves Book's integration into the Amish community as a substitute for the social structure of the police force from which he was expelled.
The Amish subculture stands in almost complete isolation from the American cultural system. It fact, it forms a counterculture based on it own values and institutions. It seems to be an interesting case-study in the social construction of technology, since the integrative forces of Amish society have for the most part rejected the technological advances that are embraced as the foundation of modern Western culture. Instead, the Amish rely on tradition as the governing factor of their society and enforce adherence to tradition by various means of social control such as shunning, exclusion from the community. While modernity and industrialization have tended to fragment society, Amish society is collectivist, both in its readiness to help Book and especially as symbolized in the community effort of the barn raising. In the climax of the film, the collectivist structure of Amish culture overwhelms the isolated recourse to violence by the corrupt police chief.
