The Purge [Behind The Scenes] 

B-roll for The Purge. Clip shows a compilation of behind the scenes footage from the film.
In the not-too-distant future, a new political regime, called the New Founding Fathers of America, attempts to control an epidemic of violence and crime by imposing strict martial law, and by trying out a new experiment called The Purge, where three times a year, for 12 hours, murder is completely legal.
