What began as a simple experiment turned into a horrific recurring nightmare… check out the first trailer for The First Purge.

Here’s the official synopsis: To push the crime rate below one percent for the rest of the year, the New Founding Fathers of America (NFFA) test a sociological theory that vents aggression for one night in one isolated community.  But when the violence of oppressors meets the rage of the marginalized, the contagion will explode from the trial-city borders and spread across the nation.

The First Purge opens July 4.
