The fourth movie in the “Purge” franchise is a prequel that goes back to when it all started.

Behind every tradition lies a revolution. Next Independence Day, witness the rise of our country’s 12 hours of annual lawlessness. Welcome to the movement that began as a simple experiment: The First Purge.

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 new movie stars Y’Lan Noel, Lex Scott Davis, Joivan Wade, Luna Lauren Velez, and Marisa Tomei.

“The First Purge” hits theaters on July 4th.
