A young Charlene "Charlie" Roan and her family are tied up by a masked purger. He taunts them with his "purge playlist", and then tells them they will play a final purge game called "Mommy's Choice." He then proceeds to kill the rest of Charlie's family and leaves her as the only survivor of her family. Eighteen years later, Roan is a United States Senator campaigning for the President of the United States, promising to end the annual purge nights. Former police sergeant Leo Barnes is now head of security for Roan. The New Founding Fathers of America's (NFFA) leader, Caleb Warrens and their candidate, Minister Edwidge Owens, view Roan as a threat; in the guise of regaining the public's trust, revoke immunity for rank 10 or higher government officials to kill her on Purge night.
