The film, directed by Gerard McMurray, is a prequel that explores the events leading up to the first Purge. It follows the New Founding Fathers of America as they test a theory that allows a community to vent its aggression for one night, with the goal of reducing the crime rate to nearly zero.

The First Purge
On Staten Island, a social experiment takes place as the newly empowered New Founding Fathers of America temporarily suspend laws for 12 hours, enticing participants with a $5,000 reward to remain on the island.
