The increasingly timely series of sci-fi-esque thrillers returns for a third outing. This time around it seems a United States Senator (Elizabeth Mitchell) is the front-runner to become the US President. Her first order of business? Eliminate the Purge, which allows Americans to commit any crime they want for one day each year. Naturally, this makes her a major target of anarchy-loving killers during this year's bloody Purge. Can Sergeant Barnes (Frank Grillo, a survivor from The Purge: Anarchy) keep her alive? 105 minutes R.
