Prince William County, Virginia becomes ground zero in America’s explosive battle over immigration policy when elected officials adopt a law requiring police officers to question anyone they have "probable cause" to suspect is an undocumented immigrant. 9500 Liberty reveals the startling vulnerability of a local government, targeted by national anti-immigration networks using the Internet to frighten and intimidate lawmakers and citizens. Alarmed by a climate of fear and racial division, residents form a resistance using YouTube videos and virtual townhalls, setting up a real-life showdown in the seat of county government. The devastating social and economic impact of the “Immigration Resolution” is felt in the lives of real people in homes and in local businesses. But the ferocious fight to adopt and then reverse this policy unfolds inside government chambers, on the streets, and on the Internet. 9500 Liberty provides a front row seat to all three battlegrounds.
