The Purge: Anarchy (Original Motion Picture Soundtrack)

One night per year, the government sanctions a 12-hour period in which citizens can commit any crime they wish — including murder — without fear of punishment or imprisonment. Leo, a sergeant who lost his son, plans a vigilante mission of revenge during the mayhem. However, instead of a death-dealing avenger, he becomes the unexpected protector of four innocent strangers who desperately need his help if they are to survive the night.
