After three films, The Purge film series continues where it all started. The First Purge is a prequel to the original, which we get a look at in this first trailer.

In the film, we see how the U.S. adopted The Purge, which implements lawlessness for 12 hours in an attempt 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.

Take a look at the first trailer up top. The First Purge hits theaters on July 4.
