After capturing an illegal act of police violence on his cellphone, a Brooklyn street hustler sets off a series of events that alter the lives of a local police officer and a star high-school athlete.
Two years after choosing not to kill the man who killed his son, former police sergeant Leo Barnes has become head of security for Senator Charlene Roan, the front runner in the next Presidential election due to her vow to eliminate the Purge. On the night of what should be the final Purge, a betrayal from within the government forces Barnes and Roan out onto the street where they must fight to survive the night.
